非终止 while 循环

2021-12-26 00:00:00 while-loop c++

我只是想知道一些事情.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 << "

The largest number is: " << largest;
    system("pause");
    return 0;
}

问题是，它永远不会终止.我确实通过稍微修改代码来解决这个问题，但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 << "

The largest number is: " << largest << endl;
    system("pause");
    return 0;
}

似乎在删除 else if 语句后它起作用了.发生了什么?

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，您将在每次迭代时将计数器重置为 1.

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