数组指针程序翻转位并加1

Question

我正在尝试编写一个程序，该程序将使用任意数字并将位翻转并加一个，并且我已经编写了代码，但是我一直遇到分段错误（核心转储）错误。有人可以看一下我的代码，看看为什么会发生此错误。我在下面附加了我的代码以及我想接收的输入和输出。

#include "stdio.h"
#include "malloc.h" //Needed for malloc, realloc, and free

#define GROW_BY 2
#define MAX_BITS 32

int add_one(int in_array[], int num){
        for (int i = 0; in_array[i] != NULL; i++) {
                int add_one = in_array[num - i] + 1;
        }
        return add_one;
}

int main() {

        //Declaration and Initialization of Variables
        int* array = NULL;

        int bit = getchar();
        int count = 0;
        while (bit != '\n') {
                bit = bit - '0';
                *array = &bit;
                array = (int*)malloc((strlen(bit) + 1) * sizeof(int));
                if (array == NULL) {
                        printf("An error has occurred and the program will now $
                        return 1;
                }
                bit = getchar();
        }

        for (int j = count - 1; j >= 1; j--) {
                if (array[j] == '1') {
                        array = (int*)realloc(array, GROW_BY * sizeof(int));
                        if (array == NULL) {
                                printf("An error has occurred and the program w$
                        }
              }
                else if (array[j] == '0' ) {
                        array = (int*)realloc(array, GROW_BY * sizeof(int));
                        if (array == NULL) {
                                printf("An error has occurred and the program w$
                                return 1;
                        }
                }
        }

        add_one(array, bit);

        for (int j = count - 1; j >= 1; j--) {
                if (array[j] == '1' && add_one == 1) {
                        array[j] = '0';
                }
                else if (array[j] == '0' && add_one == 1) {
                        array[j] = '1';
                        int add_one = 0;
                }
                else {
                        array[j] = array[j];
                }
        }


        printf("%ls/n", array);

        free(array);

        return 0;
}

Input: 101011110
Output: 010100010
