Answer 1

#include <stdio.h>
#define N_TEST 10

int main() {
    int correct_aswers[N_TEST] = { 1, 2, 3, 3, 2, 1, 1, 2, 3, 4 };
    int ans;
    int tot_marks = 0;
    
    int i = 0;

    while (1) {
        printf("Get answer on the question %d (1 - 4): ", i+1);
        scanf("%d", &ans);
        if ( ans < 1 || ans > 4) {
            printf("Uncorrect answer\n\n");
            continue;
        }
        if (ans == correct_aswers[i]) {
            tot_marks += 4;
        }
        else {
            tot_marks--;
        }
        if (tot_marks == -4) {
            printf("Sorry, you did not qualify for the admission.\n");
            break;
        }
        if (tot_marks >= 20) { 
            printf("Congratulations, you have qualified for the admission\n");
            break;
        }
        i++;
        if ( i == N_TEST) {
            i = 0;
        }
    }
    return 0;
