尝试在getline中使用int [英] Trying to use int in getline

问题描述

cout << "How many questions are there going to be on this exam?" << endl;
cout << ">>";
getline(cin, totalquestions);

这小段代码来自我创建的类中的一个函数，我需要totalquestions作为一个int，以便它可以通过for循环运行并不断询问我所问的全部问题

This small piece of code comes from a function in a class that I have created and I need totalquestions to be an int so that it can run through a for loop and keep asking the total amount of questions that I have asked.

question q;
for(int i = 0; i < totalquestions; i++)
{
    q.inputdata();
    questions.push_back(q);
}

这段代码在哪里发挥作用?有谁有想法做这项工作?

Where does this piece of code comes to play? Does anyone have any idea to make this work?

推荐答案

使用

cin >> totalquestions;

也检查错误

if (!(cin >> totalquestions))
{
    // handle error
}
