hello everyone,
Im a student having to write a C++ program and im running into an error that I have been unable to find the solution on my own. Im running into an error as I test run the program to make sure everything is still ok. The program isnt finished however at the moment it should still compile fine.
When I run this program I get the following errors:
BTW I am using VS 2005 on windows 7
