Using a do while loop , write a calculator program that reads an arithmetic such as
12+34-2+65-21=
from the user and gives you the result when it reads the equal sign.The expression can contain any number of integers and not just five as in the above example .The
only arithmetic operators used are +,-,and = .
(no strings, no arrays..) that's what they want
