Explanation

The printf() statement prompts the user to enter the number i.e the age

The scanf() statement accepts the input from the standard input device(the keyboard). %d is the format specifier that denotes that the integer data type( int) is expected as the input. The %d in the printf() statement substitutes the value of the integer variable and displays the formatted output.
