                            想改善这个问题吗？ Update the question，所以它是on-topic，用于堆栈溢出。

我不知道为什么我的程序可以在在线GDB中运行，而不能在Code：Blocks中运行。它应该允许一个人输入他们的小时费率，然后输入他们在过去4周中工作了多少小时，将这些总计加在一起并将其返回给用户。应该使用以小时为参数的函数。在Code：Blocks中，在输入第一个小时数后，它将终止程序。这是代码：

#include <iostream>
#include <iomanip>
using namespace std;

// function declaration
float getGross(float hs[], int n);

int main()
{

  float hours[4], sum;
  sum = getGross(hours, 4);
  cout << "Gross pay: $ " << setprecision(2) << fixed << sum << endl;
  return 0;

}

// function definition
float getGross(float hs[], int n)
{
  float wage, ot, total;

  cout << "Please enter your hourly wage: " << endl;
  cin >> wage;

  cout << "Enter hours worked in each of the past four weeks (hit enter after each entry): " << endl;
  //  Storing 4 number entered by user in an array

  for (int i = 0; i < n; ++i)
  {
      //  Holding the array of hours entered
     cin >> hs[i];

      int j;
      float weekPay[4];

      if(hs[i] > 40)
      {
          ot = (hs[i] - 40) * 1.5;
          weekPay[j] = (wage * 40) + (ot * wage);
          total += weekPay[j];
      }
      else
      {
          weekPay[j] = (wage * hs[i]);
          total += weekPay[j];
      }
  }

  return total;
}

最佳答案

第40行的变量int j未初始化，这会导致运行时错误。
试图清理代码：

// function definition
float getGross(float hs[], int n)
{
    float wage, ot, total = 0;

    cout << "Please enter your hourly wage: " << endl;
    cin >> wage;

    cout << "Enter hours worked in each of the past four weeks (hit enter after each entry): " << endl;
    //  Storing 4 number entered by user in an array

    for (int i = 0; i < n; ++i)
    {
       //  Holding the array of hours entered
       cin >> hs[i];

       if (hs[i] > 40)
       {
           ot = (hs[i] - 40) * 1.5;
           total += (wage * 40) + (ot * wage);
       }
       else
       {
           total += (wage * hs[i]);
       }
     }

     return total;
  }
