getline(cin，string1)问题 [英] getline ( cin, string1) problem

问题描述

大家好，
请帮我解决这个奇怪的问题.每当我在代码中调用多个getline(cin，string1)函数时，它们中的一些都会在运行时被跳过，即不提示用户输入，程序只是跳到另一行，例如
getline(cin，string1);
getline(cin，string2);
永远不会提示用户输入string1.仅提示用户输入字符串2.

Hi all,
Please, help me with this strange problem. Whenever I invoke more than one getline(cin, string1) function in my codes, some of them are skipped at run-time i.e. the user is not prompted for input and the program simply jumps to another line e.g.in
getline (cin, string1);
getline (cin, string2);
The user is never prompted for string1. The user is only prompted for string2.

推荐答案

您可以尝试在getline(cin, string1);之前调用cin.ignore();(如果输入缓冲区中有虚假的换行符) .
:)

You may try to call cin.ignore(); just before getline(cin, string1); (if you have a spurious newline in the input buffer).
:)
