浮点异常（核心转储）需要帮助确定潜在错误在哪里

Question

此函数应打印 while 循环给出的奇数和偶数输入的平均值，直到输入 0，然后结束。它目前无法运行，我将此块从与错误无关的较大代码部分中分离出来。有什么想法会给出点异常错误吗？

 int main()
{
    int numReturn;
    int evenTotal;
    int evenCount;
    int oddTotal;
    int oddCount;
    
    while(numReturn != 0){
      printf("Enter a positive integer: ");
      scanf("%d",&numReturn);
      
      if(numReturn<0){
          printf("That's a negative number!\n");
      }else if(numReturn%2 == 0){
          evenTotal += numReturn;
          evenCount += 1;
      }else{
          oddTotal += numReturn;
          oddCount += 1;
      }
    }

    double evenAvg = evenTotal/evenCount;
    double oddAvg = oddTotal/oddCount;
    
    printf("%d even numbers were entered and the average is %lf\n",evenCount,evenAvg);
    printf("%d odd numbers were entered and the average is %lf\n",oddCount,oddAvg);

   //some code for problem 1
   return 0;
}

Answer 1

当

evenCount

或

oddCount

为零时，

evenTotal/evenCount

或

oddTotal/oddCount

会被零除。很可能，这些都是整数变量，除以零会导致异常。由于历史原因，这被报告为“浮点异常”。
