Write a program, which will act as a simple four

-

function calculator. That is it will read a

number, read an operator, read another number, then

do the operation. The calculator

works with integers and uses four functions: +,

-

, *, and /. After the first operation is

completed, the program will read another operator and uses the result of the previous

operation as the first value for the next oper

ation. If the user enters a C the result is

cleared and then the user starts entering a new number. If the user enters an X, the

calculator is turned off. The various input values (i.e. numbers, operators, commands)

will be followed by the ENTER key. Your

program should prompt the user on what the

user is to do. The commands C and X may be entered in place of an operator.
