不终止的while循环 [英] Non-terminating while loop

问题描述

我只是想知道什么.我有以下代码:

I was just wondering something. I have the following code:

#include <iostream>
using namespace std;

int main()
{
    int number, largest, counter = 1;
    while (counter <= 10)
    {
          cout << "Enter a number: ";
          cin >> number;
          if (counter = 1)
          {
               largest = number;
          }
          else if (number > largest)
          {
               largest = number;
              }
          counter++;
    }
    cout << "\n\nThe largest number is: " << largest;
    system("pause");
    return 0;
} 

问题是，它永远不会终止.我确实设法通过修改代码来解决了这个问题，但是我想知道为什么会发生这种情况.这是固定代码:

The thing is, it never terminates. I did manage to fix the problem by modifying the code a little, but I was wondering why this happened. Here is the fixed code:

#include <iostream>
using namespace std;

int main()
{
    int number, largest, counter = 1;
    cout << "Enter a number: ";
    cin >> number;
    largest = number;
    while (counter < 10)
    {
      cout << "Enter a number: ";
      cin >> number;
      if (number > largest)
      {
           largest = number;
      }
      counter++;
    }
    cout << "\n\nThe largest number is: " << largest << endl;
    system("pause");
    return 0;
}

在删除else if语句后，它似乎起作用了.发生什么事了?

It seems that after removing the else if statement it worked. What happened?

推荐答案

if (counter = 1) 

应该是

if (counter == 1) 

否则，您将在每次迭代中将计数器重置为1.

otherwise, you're going to reset your counter to 1 each iteration.
