ooo... yes yes i see

btw how to loop the calculator? after one operation it just ask me to press any key to exit

[viscid canyon]

many ways, basically: put your code inside the loop

suggestion: a while loop (https://www.w3schools.com/cpp/cpp_while_loop.asp) with a condition that relies on user input every time you want to reuse your calculator.
