C++入门经典-例3.13-不加break的switch判断语句

1：不加break，会依次运行下面的语句，代码如下：

// 3.13.cpp : 定义控制台应用程序的入口点。
//

#include "stdafx.h"
#include <iostream>
using namespace std;
void main()
{
cout<<"输入一个1-7范围内的数字作为相应的星期"<<endl;
    int iInput;
    cin >> iInput;
    switch(iInput)
    {
    case 1:
        cout << "Monday" << endl;
    case 2:
        cout << "Tuesday" << endl;
    case 3:
        cout << "Wednesday" << endl;
    case 4:
        cout << "Thursday" << endl;
    case 5:
        cout << "Friday" << endl;
    case 6:
        cout << "Saturday" << endl;
    case 7:
        cout << "Sunday" << endl;
    default:
        cout << "Input error" << endl;
    }
}

运行结果：
