我有以下的 C++ 代码, 当我编译它时, 我得到“ 需要的价值” 错误。 请指出我哪里出错了 。 谢谢 。

#include <iostream.h>
#include <conio.h>
void main()
{
  clrscr();
  char r[5];
  int mark;
  cout<<"Please enter your goddamn marks";
  cin>>mark;
  r=mark>=35?"pass":"fail";
  cout<<"
"<<r;
}
最佳回答

问题就在这里:

r=mark>=35?"pass":"fail";

您不能为 chare 数组指定字符串字典。 您有几个选项 :

  • use strcpy() instead of assignment;
  • change r to be of type const char*;
  • change r to be of type std::string.

最后一个选择是迄今为止最好的选择。
