Write a C++ program to take input for month and day of the month.

The program should declare variables to store the value of month and day of month in two variables.

If the month entered is not between 1 and 12, display a message telling the user that an invalid month is entered.

If the day of the month entered is not between 1 and 31, inform user that an invalid day has been entered.

Make sure the program makes sure that the integer is entered for both the input.
