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;
}

数组指定字符串字典。 您有几个选项 :
strcpy()
instead of assignment;r
to be of type const char*
;r
to be of type std::string
.最后一个选择是迄今为止最好的选择。
