A program is required which will act as a calculator. The program should prompt the user to enter 2 integers and a code. The program should perform the following actions based on code entered.

- A code of 1 indicates that the two numbers should be added.

- A code of 2 indicates that the two numbers should be multiplied.

- A code of 3 indicates that the two numbers should be divided by the second number.

- A code of 4 indicates that the two numbers should be subtracted by the second number.

The program should then print both numbers, with an appropriate label indicating what is being printed. This process should be repeated until 2 zeros are entered. An appropriate message should then be printed to notify the user of the end of the program.
