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

Code C:
#include <stdio.h>
 
void changeMe(int *pNum);
 
main() 
{
 
	int *pNum;
 
	changeMe(pNum);
 
	printf("%d/n",*pNum);
 
}
 
void changeMe(int *pNum) 
{
	*pNum = 7;
}
