Question

what are variables in c define

Answer 1

C Programming/Variables. ...Variables are simply names used to refer to some location in memory – a location that holds a value with which we are working. It may help to think ofvariables as a placeholder for a value. You can think of a variable as being equivalent to its assigned value.

Answer 2

 In C programming, variables which are to be used later in different parts of the functions have to be declared. 

* a variable is a value that can change, depending on conditions or on information passed to the program

Variable declaration tells the compiler two things:

*  The name of the variable.
*  The type of data the variable will hold.
