试图制作一个超级超短和简单的文字 rping 游戏，但它不起作用！我的错误是：

24 error:no matching function for call to 'std::basic_istream<char>::getline(std::string&)'

并且在每一行都有if我得到的响应内容 C++ 禁止指针和整数之间的比较

我没有试图以任何形式或形式 o_o 这样做似乎无助于解决它。人们似乎让它工作，因为他们使用""而不是，''他们改变它''，它工作正常。但我一直在使用''！

对于 if 语句，您应该使用：

if(strcmp(response,"Pick up the gun"))

但实际上，如果您使用std::string

#include <string>
using namespace std;
int main()
{
  string name;
  string response;
  getline(cin, response);
  if !(response.compare("Pick up the gun"))
  {
    //Do stuff here for picking up gun
  }
}

只需使用 strcmp，阅读有关数组和取消引用的内容，并知道“A”表示 ASCI 大写 A，其中“A”表示字符串，即 ['A','null']。
