What is the difference between an if statement, an if else statement, and an if else if statement

If condition returns true then the statements inside the body of “if” are executed and the statements inside body of “else” are skipped.

If condition returns false then the statements inside the body of “if” are skipped and the statements in “else” are executed.

When an if else statement is present inside the body of another “if” or “else” then this is called nested if else.

The else..if statement is useful when you need to check multiple conditions within the program, nesting of if-else blocks can be avoided using else..if statement.
