variables in c programming

In C programming, a variable is a named location in computer memory used to hold a value that can be modified during the program execution[1](#user-content-fn-1). Variables can have different types, such as integer, floating-point, and character, which determine the kind of data the variable can store[2](#user-content-fn-2). The scope of a variable is the extent of the program code within which the variable can be accessed or declared[1](#user-content-fn-1). Variables can be declared and initialized at the beginning of the program or during the program execution, depending on the program requirements and design[3](#user-content-fn-3).
