内部分段错误但不确定如何修复

Question

目前正在尝试处理此代码以查找错误以及如何修复它们，并首次学习如何使用 GDB，

int Find11();
void PointersAreFun();

int main(void) {
  int myArray[10] = {1, 2, 3, 4, 5, 6, 7, 8, 9};
  int found = Find11();
  if (found != -1) {
    printf("The number 11 is in the table at location: %d\n", found);
  } else {
    printf("The number 11 is not in the table.\n");
  }

  PointersAreFun(myArray, 10);
  return 0;
}

int Find11(void) {
  int i = 0;
  int count = 0;
  int search = 1;
  int found = -1;
  int number = 5;
  int table[10];

  table[0] = number;
  printf("table[%i]: %i\n", count, table[count]);

  count = 1;
  while (count < 10) {
    table[count] = number++ * 2;
    printf("table[%i]: %i\n", count, table[count]);
    count++;
  }
  while (search = 1) {
    if (table[i++] == 11) {
      search = 0;
      found = -1;
    }
    if (count == i) {
      search = 0;
      found = 0;
    }
  }
  return found;
}

void PointersAreFun(int myArray[], int size) {
  printf("\nDemo on Pointers!\n");
  int anotheArray[10] = {10, 11, 12};
  int *ptrArray = NULL;
  int *ptrAnotherArray = NULL;
  ptrArray = myArray;
  printf("The first value of the array is %d\n", *ptrArray);
  printf("The first value of the second array is %d\n", *ptrAnotherArray);
}

我已确定此代码块周围的分段错误

  while (search = 1) {
    if (table[i++] == 11) {
      search = 0;
      found = -1;
    }
    if (count == i) {
      search = 0;
      found = 0;
    }
  }

但我不确定如何解决这个问题，因为变量 i 似乎继续递增，永远跳过如果（计数==我）与 GDB 调试器一样，即使计数为 10 且变量 i 等于 10，它也会继续递增。跳过第二个 if 条件

Answer 1

在您的代码中：

while( search = 1 )

你必须使用 == 来比较 search 和 1

还有一件事

int * ptrAnotherArray = NULL;
printf("The first value of the second array is %d\n", *ptrAnotherArray);

你设置指针 == NULL 然后你打印它指向的值。它使段错误
