定义 a;
输入>>a;
输出<<"[1] apples"<<endl;
输出<<"[2] pears"<<endl;
输出<<"[3] oranges"<<endl;
输出<<"[4] grapes"<<endl;
输出<<"[0] Exit";
   if(a==1){
   输出<<endl;
       输出<<"price=";
       printf("%.1f",3.00);
   }else if(a==2){
       输出<<endl;
       输出<<"price=";
   printf("%.1f",2.50);
   }else if(a==3){
       输出<<endl;
       输出<<"price=";
   printf("%.1f",4.50);
   }else if(a==4){
       输出<<endl;
       输出<<"price=";
   printf("%.1f",9.50);

整形 a;
   输出 "[1] apples" endl;
   输出 "[2] pears" endl;
   输出 "[3] oranges" endl;
   输出 "[4] grapes" endl;
   输出 "[0] Exit" endl;
   输入 a;
   如果 (a 等于 1){
       输出 "price=";
       printf("%.1f",3.00);
   }否则如果(a 等于 2){
       输出 "price=";
       printf("%.1f",2.50);
   }否则如果(a 等于 3){
       输出 "price=";
       printf("%.1f",4.50);
   }否则如果(a 等于 4){
       输出 "price=";
       printf("%.1f",9.50);
   }否则如果(a 等于 0){
       exit(0);
   }否则{
       输出 "price=0";
   }

#include<iostream>
using namespace std;
int main(){
    int n;

    cout<<"[1] apples"<<endl;
    cout<<"[2] pears"<<endl;
    cout<<"[3] oranges"<<endl;
    cout<<"[4] grapes"<<endl;
    cout<<"[0] Exit"<<endl;
    cin>>n;
    switch(n){
        case 0:
            return 0;
        case 1:
        cout<<"price=3.0"<<endl;
        return 0;
        case 2:
        cout<<"price=2.5"<<endl;
        return 0;
        case 3:
        cout<<"price=4.5"<<endl;
        return 0;
        case 4:
        cout<<"price=9.5"<<endl;
        return 0;
        default: 
        cout<<"price=0"<<endl;
    }
    return 0;
