hi
i have this assignment in c++, i did it, but there is one tiny error i cant figure out the solution to it. the program below is supposed to take in 3 elements value inputs from user for 3 students. so if you run it, you get input student1 birth month numerically, then birth day; then birth year. then id, age, and the gpa. and it loops for 3 students. however, it inputs the complete birthdate for each student when you are done inputting the 3rd student information a format of month/day/year for each student. i am getting 0/0/0. why?
#include "stdafx.h"

#include <string>

i needed this in some hours from now, and its just a simple problem here (is the get day, month, year after each slash in the code wrong? thats all i think of, but i dont know how otherwise it fixes because it didnt give me errors) so any help is appreciated!
