c++ - strcmp() 的问题没有正确比较字符串

Question

这是实际的代码，因为它似乎特定于此处的某些内容。

#include <iostream>
#include <string.h>

using namespace std;

int main()

cout << "  Just say \"Ready\" when you want to start.";
char tempReady[20];
cin >> tempReady;
length = strlen(tempReady);
char* ready = new char[length+1];
strcpy(ready, tempReady);
while((strcmp(ready, "Ready")||strcmp(ready, "ready"))!=0)
   {
   cout << "Try again.";
   cin >> tempReady;
   length = strlen(tempReady);
   delete[] ready;
   ready = new char[length+1];
   strcpy(ready, tempReady);
   }
cout << "Success";

有人看到什么不对吗？

Answer 1

C 风格的方法:

char str[256];
if (scanf("%255s", str) == 1 && strcmp(str, "hello") == 0) {
    printf("success");
}

C++ 方法:

std::string str;
if (std::cin >> str && str == "hello") {
    std::cout << "success";
}

现在决定是用 C 还是 C++ 编写代码，只是不要混用。
