Urgent HELP needed with non working C++ code

[moha85]

Hello everyone, Below is my code that is not working and the 2 errors I'm getting are error codes LNK2019 and LNK1120 but I can't figure out what is causing these errors. Please if anyone can help me as soon as possible I would be very grateful because I need this code to run. I had changed all the errors I thought I had to to get it to work but it just won't. Thanks!!!

i compiled .

doesn't have any problem. check your cpp. your other cpp didn't exclude isnt?
