Integer variables are declared by specifying the data type "int" followed by the variable name. For example, to declare an integer variable named "num", the syntax would be "int num;". This tells the compiler to allocate memory for an integer variable named "num" that can store whole numbers within a certain range. Integer variables can also be initialized at the time of declaration by assigning a value, such as "int num = 5;". **
