Assigning values to Storage class

To create a variable, specify the type and assign it a value:

Syntax

type variable_name = value;

Where type is one of C types (such as int), and variableName is the name of the variable (such as x or myName).
The equal sign is used to assign a value to the variable.

So, to create a variable that should store a number, look at the following example:

Example:

int mynum = 15;

You can also declare a variable without assigning the value, and assign the value later:

Example:

//Declare a Variable int My_num; //Assign value to variable My_num = 15;
