Integer and float conversion in C

If you want to learn good programming by mastering C languages, then you should also get information about integer and float conversion. Let's take a look at it-

   Whenever an arithmetic interaction is completed between any two integers, the result will always be the integer value.
   In the same way, the completion of the two real assumptions will result in the real value as a result.
When you complete any operation between the integer and the real, you will always get the real value in the following table you can understand it.

What is Keyword in C programming

The keywords are actually words that the compiler knows as of now, keywords can never utilize variable names. In some exceptional conditions, a few compilers can give you authorization to characterize the names of such Variables. The names are like the keywords.

The keyword is likewise called the Reserved Word. The C language has 32 keyword In this table, you can see the C language keyword.

Making Instructions in C language so far you have knowledge about various sorts of Constant Variables and Keywords. Utilizing this information, you need to figure out how to compose instructions. Under this language you can make 4 directions in the instructions Is called:

Type Declaration Instruction: Under this, the variable utilized as a part of the program is composed.

Input Output Instruction: Under these instructions, the capacities that are utilized by contributing the information into the program result as output.

Arithmetic instruction : Under these instructions, Mathematical work is proficient through constants and variables.

Control Instructions: It controls the request of execution of the announcements utilized as a part of the program.

Along these lines, you may have understood that four sorts of instructions are utilized when composing a program in a language.

Rules for making Different constants

Under the Primary Constant in C language, the constants, called number, comes out first, which must be made with a specific end goal to utilize them in the program, the accompanying principles have been recommended for any error in that structure.

   An Integer Constant must contain at least one digit.

   There ought not be any decimal in the integer constant.

   This constant has either positive values inside it or holds negative values.

   On the off chance that you don't choose the way of this consistent, then the default setting will be viewed as Positive.

   Under integer constant, coma or empty space cannot be utilized. 6 scope of integer constants range from - 32768 to 32767.

The scope of the number steady relies on upon the span of the words utilized as a part of the computer. This scope of 16 bit computers is the same, however 32 bit computers can be more in the accompanying illustration. A few examples are appearing beneath.


Rules for Creating Real Constants
In this language, Real Constant is additionally called Floating Point.These are composed in two structures, one is known as a fractional form and the second is called exponential form. To make a real constant in the fractional form, you need to take over following rules.

   Under the Real Constant, there we must have to put at least one digit.
   It is additionally compulsory to have a decimal in a real consistent.
   Real Constant will either be positive or negative.
   On the off chance that you don't utilize any sign with positive negative, then it will be considered as positive by default setting.
   Not permitted to utilize coma and empty space in real consistent.

The constant in the exponential form is made in that condition when the constant's esteem is either too little or too enormous. In this form, the real constant divided into two sections the part comes before -e called mantissa and the other one called exponent.


To make Real Constant in Exponential Forms, you need to take after these standards -

   The primary piece of this sort of mantissa portion of real constant ought to be isolated from the exponential part by the letter of the English dialect “e”.
   The melissa part is either positive or negative.
   In the event that you don't set a positive or negative with the oblige, its esteem will be  positive by default setting.
   Under the exponent, It must be contain of one digit. This digit can likewise be positive or negative, it will be positive as the default setting.
   The scope of this real constant can go from -3.4e38 to 3.4e38.

Rule for Creating Character Constant

   To make a character constant, you should utilise a letter, a digit or an uncommon symbol under an inverted comma. Both inverted commas ought to indicate the left.
   Character Constant's base size ought to be one letter.

Things To Know While Writing An Arithmetic Statement

When you use an Arithmetic statement, you have to take special care of the following:

   C language allows you to type a single and the only left of an equals sign.
Z = k * 1 This is perfect but if you write it like this
K * 1 = z then it would be wrong.
   When using a statement to lessen the character constants in the character variable, it is equivalent to the Arithmetic indicator as if:
Char a,b,d;
   In the semantic operation we can use int, float and char as:
Char , y;
Int z;
Here the characters are actually using their ASCII values. Like the A and B's ASCII values are 97 and 98.
   The operator you want to use when writing semantic instructions. It is compulsory to write it You can not assume that the operator will be used in the statement itself. In the general semantic statement, we write the process of multiplication like this:

A=c.d.b (xy)

But in C language this statement will be written in such a way-

   There is no operator in C language that will complete exponential so the following statement is incorrect -

Types Of Variables in C language

Under the program execution in C language, when an esteem transforms, it is called variable. These factors put away with a name in the memory of the computer in a similar place where the Constant Store is found. In every language, what number of variables are utilized as a part of every language, It rely on upon what number of sorts of constants it uses.

Rules for creating variables
   The name of the variable can be a group of 1 to 8 characters, in which we can utilize digits and underscores, a few compilers likewise permit the utilization of such variables, whose name is can be up to 40 characters yet remain restricted to 8 characters will be more proper.
   The primary letter of the variable ought to be an alphabet.
   Can not utilize comma and space in variable names.
   Any uncommon symbol with the exception of the underscores can not be utilized as a part of the variable. The following example shows some variable names with underscores


These rules apply to a wide range of essential and auxiliary variables. In C language, we can characterize variables diversely in the program, for e.g., in the event that we need to characterize the inside sort factors along these lines -

Int pi, n_gsb;

So also, in the event that you need to characterize float type variables, you will do along these way-

float hassall;

On the off chance that you are utilizing the character sort variable then compose it like this-

Char code:

Here you keep the names of variable names restricted to 8 characters

Arithmetic Statement in C language

Arithmetic Statement in C language is utilized as a part of three ways. Let’s consider these three sorts one by one.

Integer Mode Arithmetic Statement: All sorts of operands are used as a part of this kind of an arithmetic statement whether the number variable or integer constant. The whole number consistent can be comprehended by taking over these cases -

Int a, author, albert, code;
a = a+1;
author = albert*123 + code - 6754;

Real Mode Arithmetic Statement: All operands used as a part of this sort of arithmetic statement are either real constants or real variables. In the accompanying case, you can comprehend by taking a gander at them -


Float saee, basic, id, flow, loi;
saee = basic + 12.234/3.4*1.254;
Id = flow*loi/10.0;
Mixed mode arithmetic statement: In this kind of arithmetic statement there are a few operands are integers and few real. Following the example portrayed that case -

float pi, tine, folk, foy, avg;
int x, y, z, num;
pi = tine*foy*folk/10.0
avg = (x+y+z + num)/ 4;

In this way, you have understood that how we can compose instruction by 3 ways of using an arithmetic statement.

C++ Basics A Short Description

C++ is an Object Oriented Programming Language. C ++ was born in Bell Labs. This language was developed by Bjarne Storoustrup in the year 1983. This language has been added to the characteristics of object-oriented programming using the elements of the C language. We can say without any doubt C ++ language is upgraded version of C language. Its a general purpose object-oriented programming language.

How to Start Work in C programs language

In the event that you need to do programming in this language, then you should embrace a similar strategy which was received while taking in your English language. When we take in any language, we first get data about the letters, they are likewise called letter set. At the point when our data identified with our letters finishes, we figure out how to make words through them. Subsequent to understanding the words, we make the sentence and when we figure out how to make the sentence, we can make the total report. The programming framework in C language is additionally comparative. As a matter of first importance you have to get the data of these letters, numbers and uncommon symbols utilised as a part of programming.

After this data, the details of Constant, Variable and Keyword must be acquired. After this data is finished, they figure out how to compose guidelines and when they are aced in composing the instruction then figure out how to compose programs. Along these lines we can learn C programming. Give us now a chance to study every one of these components in this language deliberately.

First install C compiler in your computer before starting C programming 
Start your first C Program 
type in compiler

   int main()
      printf(“Hello my first c program\n”);
    return 0;

Run this program
Looking on your screen - Hello my first c program
You build successfully your first C program


Introduction on Character Group of C Language

  • In this language, from A to Z, all letters can be utilised to give instructions. This letter can be both capital letter (A, B, C ....) and small letters (a, b, c ...).
  • When we take a gander at points, it can utilise any digit from 0 to 9.
  • The following is utilised as a part of programming, in unique symbols.
       ~ ‘’ ! @ # % ^ & * ( ) _ - + = { }
       [] :: “ ‘ <> ; . ? /

   Constant, Variables and Keywords

In C language these three are made one after another in order by letters and exceptional symbols. The esteem set under the Constant does not change under any conditions. Or maybe it stays stable. The esteem that is set under it is put away in the computer's memory. Interestingly, store values shift in factor. Factors additionally store the memory of the computer by giving a name like the steady. In the accompanying case, you can comprehend this -

3a + 2b = 25
Here 3, 2 and 25 is Constant, it won't change while a and b are variable and its esteem will change. Along these lines, you have understood the contrast amongst Constant and Variable.

Different Types of Constant
To make programming less demanding in C language, Constant is partitioned into two classifications. This class is beneath

Primary Constant
Secondary Constant

Both of these classes contain distinctive sorts of constants inside them. Under the essential steady, the number constants, the genuine consistent and the character Constant come. Though Constant like Array, Pointer, Structure, Union and Enum under auxiliary steady comes. In the accompanying picture you can understand them well -

Introduction of C Programming Language - C Basic

When we characterize programming in the specialized dialect of the computer, then it is said that the group of instructions given in in the order given to the computer is called programming. These guidelines require a dialect to get to the computer. Keeping this requirement in mind, the language named C was developed in the USA in 1972 at AT & T Bell Lab. This language was made by Dennis Ritchie named Scientist. Prior to that dialect ​​used for programming, C was brimming with every one of those dialects ​​and its course kept on expanding. Its exceptional reason was that it was simple and dependable. To offer instructions to computers, language ​​development began from 1960. In the event that we take a gander at its improvement then we will find that the initial four noteworthy language ​​were utilized -

  • In the 1960's, the International Committee built up the language called ALGOL.
  • In the year 1963, the language of CPL was created at Cambridge University.
  • In 1967, Martin Richard of the University of Cambridge built up a language called BCPL.
  • A language named B was created by Ken Thompson in the AT and T research center in 1970. In the year 1972, the language named S has been created by Dennis Ritchie AT and T Laboratory

When we take a gander at the attributes of the language, we find that it neither comes into the class of high level language nor is it totally in the lower level language classification. Actually, it takes the way between the two. On account of which them two have the insight. When we contrast it with Machine Oriented languages, we find that it is exceptionally able in programming, and when we contrast it with Problem-situated languages, we find that it is more equipped to coordinate the machine contrasted with them. Is there. With this you can figure the attributes of this language.
