Answer 1

#include <stdio.h>
#include <stdlib.h>

int main()
{
    const char* arr_string[] = { "7", "0", "55", "8", "9", "6" };
    int arr_int[] = { 0, 0, 0, 0, 0, 0 };

    int size = sizeof(arr_string) / sizeof(arr_string[0]);

    for (int i = 0; i < size; i++) {
        arr_int[i] = atoi(arr_string[i]);
    }

    for (int i = 0; i < size; i++) {
        printf("%d ", arr_int[i]);
    }

    return 0;
