int main(int argc, char *argv[])
{
    int target[2], i, j, count[2], len;
    for (target[0] = 'A', target[1] = 'a'; target[0] <= 'Z', target[1] <= 'z'; target[0]++, target[1]++)
    {
        count[0] = 0;
        count[1] = 0;
        for (i = 1; i < argc; i++)
        {
            len = strlen(argv[i]);
