C: Passing pointer to function which sets value and printing it

.NET
1

Figured one of you dot net developers might be able to assist me with a c question. I can not for the life of me figure out how to print the value. I keep on getting a Segmentation fault error when running this code. Though it compiles perfectly fine.

Thanks


#include <stdio.h>

void changeMe(int *pNum);

main()
{

	int *pNum;
	
	changeMe(pNum);
	
	printf("%d/n",*pNum);
	
}

void changeMe(int *pNum)
{
	*pNum = 7;
}
