Answer

The order in which the statements of a program are executed is known as control flow. By default, the statements of a program are executed from top to bottom in order in which they are written. But most of the times our programs require to alter this top to bottom control flow based on some condition. The statements that help us to alter the control flow of the program are known as conditional statements.
