介绍C程设计的一典型案例：例如编写一些小游戏

#include<stdio.h>
int main(void)
{
	int money,i,j,k,fen5,fen2,fen1,count;
	fen5=5;
	fen2=2;
	fen1=1; 
	count=0;
	printf("Input money:");
	scanf("%d",&money);   
	if(money>=8&&money<=100)
	{
		for(i=1;i<=20;i++)
		{
			for(j=1;j<=50;j++)
			{
				for(k=1;k<=100;k++)
				{
					if(money==i*fen5+j*fen2+k*fen1)
					{
						count++;
						printf("fen5:%d,fen2:%d,fen1:%d\n",i,j,k);
					}
				}
			}
		}
	}
	printf("count=%d\n",count);
	return 0;
}
