In this lab we ask the user to enter two integer numbers. Then ask the user to make a choice which operation wants to make (addition, subtraction, division, multiply, remainder,  or show if the first number is greater, less than or equal to the second number. after this operation is complete the program should restart and ask the user for the new values. If the user press 0 as his choice the program ends.
