#include<stdio.h>
int main(void)

    int choice,i;
    double price;

    for(i=1;i<=5;i++){
        printf("[1] Select apples \n");
        printf("[2] Select pears \n");
        printf("[3] Select oranges \n");

        printf("Enter choice:");
        scanf_s("%d",&choice);

        if(choice==0)
            break;

        switch(choice){/*利用switch,break显示各项*/
        case 1:price=3.00;
            break;
        case 2:price=2.50;
            break;
        case 3:price=4.10;
            break;
