What Is an Integer Variable?

Integer variables are a computer language. In the C language, the value of an integer variable can be decimal, octal, or hexadecimal, but it is stored as a binary number in memory. Variables, as their name implies, are values that can be changed. Integer variables represent integer-type data.

Representation

The general form of an integer variable variable description is

Type specifier variable name identifier, variable name identifier, ...;

Integer variables e.g.

int a, b, c; (a, b, c are integer variables)

long x, y; (x, y are long variables)

unsigned p, q; (p, q are unsigned integer variables)

Integer variables define the format of integer variables as

Integer type 1 variable name or multiple variable names separated by commas

Similarly, you can also define unsigned int, unsigned long variables.

Defining a variable means allocating a corresponding amount of storage space to the variable in memory, as well as determining how the variable value is stored and the operations that can be performed.
