Question

有人能帮助我吗？我想制作一个程序，问我“第一个是什么？”，“第二个是什么？”，“第三个是什么？”我希望它能像我告诉它的那样多次问我。它存储在int noftimes。

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

int main()
{
    //Get number of grades.
    int nofgrades = 7;
    cout << "How many grades do you want to calculate?\n";
    cin >> nofgrades;
    //Get grades.
    cout << "What's the " << (nofgrades - (nofgrades - 1)) << "st grade?\n";
    //Calculate average.

    //Display average.


    return 0;
}

我正在用C ++编程。感谢所有帮助。

在这里，通过使用for循环，您可以轻松地执行所要求的操作。阅读有关for循环和一般编程原理的更多信息。查看this subreddit侧边栏以获取良好的资源。

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

int main()
{
    //Get number of grades.
    int nofgrades; // Why did you initialize it when you're going to override it anyway?
    cout << "How many grades do you want to calculate?\n";
    cin >> nofgrades;
    //Get grades.
    for (int i = 1; i <= nofgrades; ++i) {
        cout << "What's the " << i << "st grade?\n";
        //Load aditional grades... 
    }
    //Calculate average.

    //Display average.


    return 0;
}
