Make this code better
Calclator using switch statement for various operations
I designed and devised this calculator on my own, from scratch. My idea is to let the user choose the operation they want to perform on the two numbers they will input, and the computer will then output the statement corresptonding to each case.
The code compiles and everything, but when I try to select the operation, the process stops responding, and I am forced to quit it manually. Any help is much appreciated.
