#include<stdio.h>
int main()
{
	int i,j,k,l=0;
	printf("\n");
	for(i=1;i!=5;++i)
	{
		for(j=1;j!=5;++j)
		{
			for(k=1;k!=5;++k)
			{
				if(i!=j&&i!=k&&j!=k)
				{
					printf("%d%d%d\t",i,j,k);
					++l;
					if(0==l%5)
					{
						printf("\n");
						
					}
					
				}
			}
		}
	}
	printf("%d\n");
	return 0;
}

You might try displaying l. I can't see you ever use it in the code

BTW: I would avoid using variable names that look like numbers. l is a poor choice.
