Thread: I Need Help

hey
Im useing Microsoft Visual C++ 6.0 to program a C program (i think this is the problem ) but anyway i dont have a choice. The problem is very simple but I cant figure it out.
I have three files
header
main
and the one that my functions are defined in and when I compile I get a error saying
lab2.obj : error LNK2001: unresolved external symbol "int __cdecl SetSwitchParm(void)" (?SetSwitchParm@@YAHXZ)
Debug/lab2.exe : fatal error LNK1120: 1 unresolved externals
Error executing link.exe.

Code:

This is the .h
#define MAX 32

void SetSwitchParm(void);

struct Switch {
	
	int iProbStateChange[1];
	int iProbGlich[1];
	int iDebouncer[1];
	int iPresSateSwitch[1];

}SwitchData[MAX];

THe .c - file where the functions are defined
#include <stdio.h>
#include <stdlib.h>
#include "Switch.h"

void SetSwitchParm(void)
{
	int lol;
	lol= 8;
	printf("\n\n\n\nit works\n");
	return 0;
}

int GetSwitchParm(int iSwitchID, int iParm)
{
	return 0;
}
and the main 
#include <stdio.h>
#include "Switch.h"
#include <stdlib.h>

int main()
{
	int iNumSwitches;
	int h;

	SetSwitchParm();//this is the part that wont work 
	{
		printf("Please enter the number of switches: ");
		scanf("%d", &iNumSwitches);

	
		if(iNumSwitches > 32){
			printf("Please try again the program accepts switches from 1 to 32,\n");
			printf("you have entered %d. Please try again.\n\n", iNumSwitches);
		
		}
		if(iNumSwitches <= 32)
			break;
	}
	printf("\nhi\n");
	return 0;
}

Thanks Guys

You need to make sure BOTH your .c files are in the project

It turns out, this is wrong if you want to compile as C. The ".cpp" extension means, naturally, to comple as C++. There is a difference.

Quzah.
