csharp:switch语句和C/C++不同

代码如下:

using System;
class TestSwtich
{

    privatestatic void Main(string[] args)
    {
       const string myName ="karill";
       const string sexName ="sexName";
       const string sillName ="sillName";
       string name;
       Console.WriteLine("What's yourname?");
       name = Console.ReadLine();
       name = name.ToLower();
       Console.WriteLine("inputname:{0}",name);

        
       switch(name)
       {

           case myName:
               Console.WriteLine("you have the same name asme!");
               break;
           case sexName:
               Console.WriteLine("my,what a sexy name youhave!");
               break;
           case sillName:
               Console.WriteLine("that 's a verysillName!");
        & #160;      break;
           default:
               break;

       }
       Console.WriteLine("hello:{0}",name);
       Console.ReadKey();

    }
}

在C/C++里swtich表达式是不能是字符类型的,只能是整型值的表达式.

代码如下:

#include <iostream>
#include <string>

using std::string;
using std::cout;
using std::endl;
using std::cin;

int main(int argc, char *argv[])
{
    stringstr;

    cout<<"input integernumber:";

//   scanf("%d",&a);
   cin>>str;

    switch(str){

    case1:cout<<"Mondayn";

    case2:cout<<"Tuesdayn";

    case3:cout<<"Wednesdayn";

    case4:cout<<"Thursdayn";

    case5:cout<<"Fridayn";

    case6:cout<<"Saturdayn";

    case7:cout<<"Sundayn";

   default:cout<<"errorn";

    }

    return0;
}
