C++无限循环

我正在尝试编写一个循环，该循环将重复直到用户输入正确的选择之一(1 或 0).出于某种原因，当我编写如下循环时，它会创建一个无限循环.

I am attempting to write a loop that will repeat until the user enters one of the correct choices (either 1 or 0). For some reason when I have the loop written as below it creates an infinite loop.

我打算让循环只在 control is not 0 OR not 1 时执行，但由于某种原因，它总是会执行并变成无限循环.

I am intending for the loop to only execute while control is not 0 OR not 1, but for some reason it will always execute and becomes an infinite loop. 

cout<<"Please enter 1 for another customer or 0 to quit : ";
cin>>control;

  while ((control != 0 )|| (control != 1))
    { 
      cout<<"Invalid Entry! Please enter a 1 to enter another customer or 0 to quit: ";
      cin>>control;
    }

我将其更改为 while control 小于 0 或大于 1，这可行，但我仍然对为什么另一个循环不起作用感到困惑.

I changed it to be while control less than 0 OR greater than 1, which works but I am still confused as to why the other loop is not working.

推荐答案

你必须使用 &&操作员.

You have to use && operator.

while ((control != 0 ) && (control != 1))
