} s[3];

int main() {
    int i;
    printf("Enter information of students:\n");
    for (i = 0; i < 3; ++i) {
        s[i].roll = i + 1;

    for (i = 0; i < 3; ++i) {
        printf("\nRoll number: %d\n", i + 1);
        printf("First name: \n");
        puts(s[i].Name);
        for (int j = 0; j < 3; j++) {
