내 소개의 C++ 클래스에 대한 최종 프로젝트를 진행하고 있으며 코드에 문제가 있습니다. getline은 제대로 작동하지 않는 것 같습니다. 다른 시간대와 다른 곳에서 본 것처럼 정확하게 입력했습니다. 여기에 질문이 실행getline을 사용하는 데 문제가 있습니다
if (groceryMenu == 2)
{
string groceryItem;
system("CLS");
cout << "Enter what you would like to add to the grocery list: " << endl;
getline(cin, groceryItem);
groceryVector.push_back(groceryItem);
코드의 섹션이의 COUT 라인은 화면에 보여줍니다 (그것은 단지 깜박하지만, 당신이 그것을 유지 볼 수 후 시스템 ("PAUSE")를) 다음 있지만, if 루프를 빠져 나와 주 루프로 돌아갑니다. 나는 내가 여기서 잘못하고있는 것을 알아낼 수 없다. 어떤 도움을 주신 것입니다 :)
여기 내 코드의 나머지는 도움이된다면. 나는 그것이 거친 것을 안다. 방금 시작 했어. 당신이 을 할 수 있기 때문에
