#define NS 4 /* number of sports */

int main(void) {
    char result, survey[NP], most;
    int i, pop, freq[NS] = { 0 };
    const char *sports[NS] = {

    for (i = 0; i < NS; i++)
        printf("%c: %s%s", 'A' + i, sports[i], (i + 1 < NS) ? "; " : "\n");

    for (i = 0; i < NP; i++) {
        printf("Person %d: ", i + 1);
        scanf(" %c", &result);
        survey[i] = result;
        if ( !(result >= 'A' && result <= 'D') )
            return 1;
        freq[result - 'A']++;
        if (i == 0)
            most = result, pop = 1;
        else if (freq[result - 'A'] > pop)
