Thread: Simple (i think) question

Hi all,

I'm writing C++ (which I hope to later compile with a Unix C compiler) and just want to compare command line arguments:

Code:

#include "stdafx.h"


int _tmain(int argc, _TCHAR* argv[])
{
	char* outputdirectory;
	char* searchdirectory;

	for (int i=0;i<argc;i++)
	{
		if (strcmp(argv[i],"-o"))
			outputdirectory = argv[i+1];
		else if (strcmp(argv[i],"-d"))
			searchdirectory = argv[i+1];


	}
}

But I get this compiler error:

Error 1 error C2664: 'strcmp' : cannot convert parameter 1 from '_TCHAR *' to 'const char *' 20
Error 2 error C2440: '=' : cannot convert from '_TCHAR *' to 'char *' 21

Does anyone have a thought? I'm guessing it's something simple I'm overlooking, or that I need to do some character conversion?

Thanks...

It's all TCHAR or all char. Choose one. (And if you choose TCHAR, you'll have to use the TCHAR version of strcmp, whose name escapes me at the moment. And the TCHAR version of string literals instead of "just things in quotes.")

The short answer is, overwrite the Visual Studio's default main header and replace with:

Code:

int main(int argc, char *argv[])
