Answer 1

The reason why you have the error is because your add function is defined after your using it in main if you were to create a function prototype before main up above it with public int Add(int x, int y); or you could just copy and paste your entire Add function above main cause main is where the compiler starts execution so doesn't it make sense to declare and define a function before you use it hope that helps. :D
