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 i,choice;
	for(i=1;i<=5;i++)
	{
		printf("[1]apple\n[2]pear\n[3]orange\n[4]grape\n[0]exit\nEnter your choice:");
		scanf("%d",&choice);
		if(choice==0)
			break;
		switch(choice)
		{
		case 1:printf("price=3.00元/千克\n");break;
		case 2:printf("price=2.50元/千克\n");break;
		case 3:printf("price=4.10元/千克\n");break;
		case 4:printf("price=10.20元/千克\n");break;
		default:printf("price=0元/千克\n");break;
		}
	}
	return 0;
}
