To define a variable, type the data type of the variable followed by a white space, the name of the variable and a semicolon.

    Such a variable can be initialized later, but it can also be initialized in the declaration itself. Of course, the value of the expression must be of the same data type as the variable.

    Both cases of variable declaration and initialization are shown below:

    • dataType variable;
      variable = expression;

    • dataType variable = expression;

    Example 66.16. Variables

    int a;
    a = 27;
    int b = 32;
    int c = a;
