    int arr2[] = "########";
    int left = 0;
    int right = strlen(arr1) - 1;

        arr2[left] = arr1[left];
        arr2[right] = arr1[right];

Answer 1

#include <stdio.h>
int main(void)
{
    char arr1[] = "welcome!";
    char arr2[] = "########";
    int left = 0;
    int right = strlen((char *)arr1) - 1;
    while (left <= right)
    {
        arr2[left] = arr1[left];
        arr2[right] = arr1[right];
        printf("%s\n", arr2);
        left++;
        right--;
    }
    return 0;
}

你存的是字符,外面应该声明为char数组
