Hy, am new here!i was searching for how to create a calculator and i discover your site,in fact is is highly fascinating,am really impressed by this work of yours with some examples that are simple to understand.but i found an error which you did not include based on line "12" which is:
cout<<"please enter operation to be performed .:(+,-,*,/,%)
so what i added was cout<<"please enter operation to be performed .:(+,-,*,/,%)";
