C++基本字符串输入输出

Question

好的，我有一个简单的在线编程作业，该作业已通过自动评分工具进行检查。大多数都非常简单，但我无法完成这项任务。这是提示和我的代码。我有一种感觉，我错过了一些相当简单的东西。感谢您的帮助。

Students just took a short, two question, multiple choice quiz. Both questions needed to >be answered correctly to receive credit. As their grader, you must determine whether >students got credit or not. The correct answers were A and D.

Input

The students' answers, sepated by a space.

Output

"Credit" or "No credit"

Example

Input:A C

Output:No credit

---

我的代码:

#include <iostream>
#include <string>
using namespace std;

int main()
{
    string input;
    cin >> input;
    if (input == "A D")
    {
        cout << "Credit";
    }    
    else 
    {
        cout << "No credit";
    }
    
    return 0;
}

Answer 1

std::cin 将在遇到新行 \n 或空格时停止搜索输入。为了获得整行输入，使用std::getline:

std::string input;
std::getline(std::cin, input);
