干扰getline功能的东西？(Something interfering with the getline function?)

我是代码和这个网站的新手，所以如果我忽略了一些明显的东西，请原谅我。我一直在尝试用c ++编写一个简短的小游戏，我需要接受用户输入。我想接受多个单词，所以我的书推荐的cin>>命令就出来了。我通过研究发现的最好的东西是getline(cin,var); 命令。我可以轻松地在小规模测试中使用它，但是当我将它实现到我的500系列游戏时，它永远不会起作用。它将跳过该位代码而不等待用户输入，并将变量设置为空白。我不会明显包含整个代码，但这里有问题，我的标题。

#include <cstdlib> #include <windows.h> #include <iostream> #include <string> using namespace std; string poemend; int heading; int poem() { system("CLS"); cout<<"This poem is almost done, you just can't seem to find the perfect last word.\n"; cout<<"You can see several of your discarded endings. Most recently, 'pain'.\n\n"; cout<<"How about another go?\n>"; getline(cin,poemend); system("CLS"); cout<<"The Prophet's old parrot spoke much of all things,\n"; cout<<"but when asked about love, squawked only "; cout<<poemend<<" .\n\n"; Sleep(6000); cout<<"You decide it could still use some work"; Sleep(3000); heading = 6; }

再次，如果我把它带到一个新的空白页面，这是完美的，所以我真的不确定是什么阻碍了。我很乐意回答有关代码的任何问题，并在需要时发布更多有用的内容。非常感谢您花时间阅读本文！

I'm new to code and this website, so please forgive me if I'm overlooking something obvious. I've been trying to write a short little game in c++, and I need to take in user input. I want to take in more than one word so the cin>> command my book recommends is right out. The best thing I have found through research is the getline(cin,var); command. I can get this to easily work in small scale tests, but when I implement it in to my 500 line game, it never works. It will skip right over that bit of code without waiting for user imput, and set the variable to a blank space. I won't include the whole code obviously, but here is the bit in question, and my headers.

#include <cstdlib> #include <windows.h> #include <iostream> #include <string> using namespace std; string poemend; int heading; int poem() { system("CLS"); cout<<"This poem is almost done, you just can't seem to find the perfect last word.\n"; cout<<"You can see several of your discarded endings. Most recently, 'pain'.\n\n"; cout<<"How about another go?\n>"; getline(cin,poemend); system("CLS"); cout<<"The Prophet's old parrot spoke much of all things,\n"; cout<<"but when asked about love, squawked only "; cout<<poemend<<" .\n\n"; Sleep(6000); cout<<"You decide it could still use some work"; Sleep(3000); heading = 6; }

Again, this works perfectly if I take this in to a new blank page, so I'm really not sure what is getting in the way. I will be happy to answer any questions about the code and post more helpful bits of it if needed. Thank you so much for taking the time to read this!
