I am getting the following error and cannot get rid of it I have spent hours looking at it but cannot find a solution wondering if anyone can help?

Linking F:\PAY.EXE:
Linker Warning: No module definition file specified: using defaults
Linker Error: Undefined symbol _main in module WINMAIN

[shadow123]

Look at your project settings. Your Project should be linked to a console application. The error message says that the linker expects a WinMain function as main entry point for a WIN32 application instead of a "normal" main function.

Tried tinkering around in Borland but still no luck, thanks for the advice though.

You don't have a main function. Where is your program supposed to begin?

This:
void main();
declares the existence of a function called main that takes no parameters and returns none. It is not an actual main function.

I suspect you meant this:

void main()
{
...
...

which is still wrong, as in C++ main must return an int, so try this instead:

int main()
{
...
...

As it is, you're clearly using a C++ compiler from before 1998. What your compiler considers to be C++ has not been C++ for a very long time. Consider getting a modern C++ compiler for free to replace it.

I know it's the program we use at college so I haven't got control over what we make the programs in. Also I changed the void main to an int main and I am still receiving the same error

[Moschops]

Your college chooses to teach outdated (i.e. wrong) C++ when they could be teaching modern (correct) C++ for free. Harsh, but sadly not uncommon.

Did you also remove the semi-colon, like I said, and also wrap your code inside the main function, like I said?

Here is a simple example.

What you did:

void main();

// Code here 

What I suggested

int main()
{

  // Code here

}

You will note that some of your other function suffer the same problem:

Bad:
void close();
Good:
void close()

Bad:
void input();
Good:
void input()

Likewise wage and slip. You need to go back to the basics of how to write a function and make sure that you're putting the semi-colons in the right place, and understand the difference between a function prototype and the actual function.

Edit:
As an aside, you keep saying "procedure"; the far more common term in C++ is function (I see "method" as well, but that seems to be more common in C and Obj-C circles).

Oh okay , thanks for the help tremendously I will begin bringing in my laptop to code from now on , I always thought we were using an outdated program but not this bad , thanks for the reality check.
