Switch语句不会打印字符串

Question

char gamerCentral::getGamerTag( )
{
    switch(gamerTag)
            {

        case '1':  return gamerTag = "Diamond";  
                    break; 
        case '2':  return  gamerTag = "Silver";
                    break; 
        case '3':  return  gamerTag = "Bronze";
                    break; 
        case '4':  return  gamerTag = "Wood";
                    break;    
        default:   return  gamerTag = "Uninstall";

        break; 
            }

 char   gamerTag;

GamerClub::GamerClub(
        char tag)
    {
    gamerTag = tag;


}

我正在尝试返回gamerTag，但它说它无法转换为字符串。他们的方法是将char转换为switch语句中的字符串吗？

Answer 1

让你的函数返回一个字符串，它仍然可以作为输入操作单个字符。这是一个例子。

std::string getGamerTag(char t)
{
   switch(t)
   {
      case '1': return "Diamond";
      case '2': return "Silver";
      // ...
   }

   return "";
}

// prints "Silver"
cout << getGamerTag('2');

Answer 2

使用字符串变量或使用char *

char* getGamerTag(int t)
{
   switch(t)
   {
      case 1: return "Diamond";
      case 2: return "Silver";
   }
}
int main()
{
    cout << getGamerTag(2);
}

我建议使用字符串数组：

std::string getGamerTag(unsigned int t)
{
  static const char * tag_names[] =
  {
    "Diamond", "Silver", "Bronze", "Wood", "Unistall",
  };
  static const unsigned int name_quantity =
    sizeof(tag_names) / sizeof(tag_names[0]);

  std::string name;
  if ((t > 0) && (t <= name_quantity))
  {
    name = tag_names[t - 1];
  }
  return name;
}
