如何使用用户输入的变量终止for循环 [英] How do I terminate a for loop with a variable the user inputs

问题描述

我有这段代码，当用户为K输入一个数字时，我试图退出，如何用这个数字终止循环？

 for（int K = 0; K< = 9; K ++）
 {
 cout<< 输入卡路里，脂肪，蛋白质和其他的量<< ENDL; 
 cout<< 卡路里：<< ENDL; 
 cin>> C; 
 cout<< 脂肪：<< ENDL; 
 cin>> F; 
 cout<< 蛋白质：<< ENDL; 
 cin>> P： 
 cout<< 其他：<< ENDL; 
 cin>> O; 
} 

我的尝试：



我尝试过使用不同的循环，似乎没有任何工作

自用户没有为 K 输入任何内容，我担心我们无法帮助您。

您需要优化详细信息你试图做什么。



对于我所看到的，循环的可以完全删除。

I have this piece of code that I am trying to exit when the user inputs a number for K, how to i terminate the loop with that number?

for ( int K=0; K<=9; K++)
   {
    cout << "Enter the amount of Calories, Fats, Proteins & Other" << endl;
    cout << "Calories:" << endl;
        cin >> C;
    cout << "Fat:" << endl;
        cin >> F;
    cout << "Protein:" << endl;
        cin >> P;
    cout << "Other:" << endl;
        cin >> O;
    }

Since the user do not input anything for K, I fear we can't help you on this.
You need to refine the question with details on what you try to do.

For what I see, the for loop can completely be removed.
