Compraring Char array without using strcmp in C

Question

I am looking for a way to compare 2 char arrays without strcmp. Is this the way to go? Or am I missing something? When I compiled it, if I type in the same strings in both, the program gets stuck and won't do anything. PLEASE HELP!

int compare_info(char *array1, char *array2)
{
    int i;
    i = 0;

    while(array1[i] == array2[i])
    {
        if(array1[i] == '\0' || array2[i] == '\0')
            break;
        i++;
    }

    if(array1[i] == '\0' && array2[i] == '\0')
        return 0;
    else
        return -1;
}

Here you have a solution, is prety like your code, but I have made some changes. I took out the returns in the middle of the loop, because they break the structure, in this way it is easier to analyze. Finishing, I added a new condition to the while, so when the end of string is found, the loop ends

int compare_info(char *array1, char *array2)
{
    int i;
    int response = 0;
    i = 0;

    while(array1[i] == array2[i] && response == 0 )
    {
        if(array1[i] == '\0' || array2[i] == '\0'){
            response = 1;
        }
        i++;
    }

    return response;
}
