Nested if-else Statements

In this kind of statement, a number of logical conditions are tested for taking decisions. Here, the if keyword followed by an expression is evaluated. If it is true, the compiler executes the block following the if condition; otherwise, it skips this block and executes the else block. It uses the if statement nested inside an if-else statement, which is nested inside another if-else statement. This kind of nesting can be limitless. The syntax of a simple nested if-else statement is shown in Figure.
