在用c ++调试程序时，我得到一个空白屏幕(I get a blank screen when debugging a program in c++)

现在发生的事情（在编辑代码之后）是每当我键入多个单词时，它就会出现痉挛。任何修复？谢谢。对不起，如果我好像什么都不知道。昂贵的书籍和没人教我，让我在线阅读教程。（编辑后的代码如下。）

#include <iostream> #include <string> using namespace std; string qu; int y; int main() { y = 1; while (y == 1) { cout << "Welcome to the magic 8-ball application." <<"\nAsk a yes or no question, and the 8-ball will answer." << "\n"; cin >> qu; cout << "\nProccessing...\nProccessing...\nProccessing..."; cout << "The answer is...: "; int ans = (int)(rand() % 6) + 1; if (ans == 1) cout << "Probably not."; if (ans == 2) cout << "There's a chance."; if (ans == 3) cout << "I don't think so."; if (ans == 4) cout << "Totally!"; if (ans == 5) cout << "Not a chance!"; if (ans == 6) cout << "75% chance."; system("CLS"); cout << "\nWant me to answer another question?" << "(1 = yes, 2 = no.)"; cin >> y; } return 0; }

Now what happens(after editing code) is whenever I type in more than one word, it has spasms. Any fixes? Thanks. Sorry if I seem like I don't know anything. Expensive books and nobody to teach me has me reading tutorials online. (The edited code is below.)

#include <iostream> #include <string> using namespace std; string qu; int y; int main() { y = 1; while (y == 1) { cout << "Welcome to the magic 8-ball application." <<"\nAsk a yes or no question, and the 8-ball will answer." << "\n"; cin >> qu; cout << "\nProccessing...\nProccessing...\nProccessing..."; cout << "The answer is...: "; int ans = (int)(rand() % 6) + 1; if (ans == 1) cout << "Probably not."; if (ans == 2) cout << "There's a chance."; if (ans == 3) cout << "I don't think so."; if (ans == 4) cout << "Totally!"; if (ans == 5) cout << "Not a chance!"; if (ans == 6) cout << "75% chance."; system("CLS"); cout << "\nWant me to answer another question?" << "(1 = yes, 2 = no.)"; cin >> y; } return 0; }
