The above is broken.  If the ar[4] is "aac" rather 
than "abc" it fails.

#include "stdio.h"

#define CountOf(a) (sizeof(a)/sizeof(*a))

int main(int argc, _TCHAR* argv[])
{


	char data[] = "abc";
	char test[CountOf(data)];

	printf("Enter %d characters: ", CountOf(data)-1);
	scanf("%s",  test);

	for (int i=0;i < CountOf(data);i++)
	{
		for (int j=0;j < CountOf(data);j++)
		{
			if (data[i] == test[j]) 
			{
				test[j] = 0; 
				break;
			}
		}
	}

	for (int i=0;i < CountOf(data);i++)
	{

		if (test[i]) {
			printf("\nNot ");
			break;
		}
	}
	printf("\nAccepted");

	return 1;
}
