Simple application technology (2)

#include<stdio.h>
main()
{int i,k=0;
for(i=1;i<=25;i++)
	{printf(" #");
	k++;
	if(k==5)
		{printf("\n");
		k=0;
		}
	}
getchar();
getchar();

}

　　This is another application of the algorithm technology, the first of several specified data perform certain operations, has extensive application value.
