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
