看注释.

 #include <stdio.h>

int main() {
    int n, count = 0, i;    //n is the number of input
    scanf("%d", &n);
    struct birth {
        char name[6];
        int year;
        int month;
        int day;
    }a, max, min;
    max.year = 2014, max.month = 10, max.day = 7;
    min.year = 1814, min.month = 8, min.day = 1;

    for (i = 0; i<n; i++) {
        scanf("%s %d/%d/%d", &a.name, &a.year, &a.month, &a.day);
        count++;
        if ((a.year>2014) || (a.year == 2014 && a.month>9) || (a.year == 2014 && a.month == 9 && a.day>6) || (a.year<1814) || (a.year == 1814 && a.month<9) || (a.year == 1814 && a.month == 9 && a.day<6)) {
            count--;
            continue;
        }
        if ((a.year<max.year) || (a.year == max.year&&a.month<max.month) || (a.year == max.year&&a.month == max.month&&a.day<max.day)) {
            max = a;
        }
        //下方第二个逻辑判断把min错写成了max，写的时候没注意看吧
        if ((a.year>min.year) || (a.year == min.year&&a.month>min.month) || (a.year == min.year&&a.month == min.month&&a.day>min.day)) {
            min = a;
        }
    }
    printf("%d", count);
    if (count != 0) {
        printf(" %s %s", max.name, min.name);
    }
    return 0;
