Heya. I'm pretty much new to the gamedev.net forums, but I've read a few things on here, and I thought I could get some help on an assignment I have in my C++ class at school. I have to create a program with something similar to the following prompt: Create a program that has a Student struct with 3 components: last name, ID number, and test grade. Create a Student type array with 5 elements for 5 students. Do not allow the user to have 2 of the same ID #'s. I thought at first that I had it all figured out, and then I ended up spending well over 6 hours trying to make it right. I did great on the inputting student information. What's stumping me is the comparing of ID numbers to see if there are any duplicates. I don't know how to do it. Here's what I've come up with in a separate program I'm doing to try and figure it out: // examination_solution.cpp : Defines the entry point for the console application. // #include "stdafx.h" #include<conio.h> #include<iostream> using namespace std; int main() { const int MAX = 5; int idNumbers[MAX]; int x; int i; int isIdentical = 1; for(x = 0; x < MAX; ++x) { cout<<"Enter user #"<<x + 1<<"'s ID Number: "; cin>>idNumbers[x]; } for(x = 0; x < MAX; x++) { for(i = 1; i < MAX; i++) { while(isIdentical == 1) { if(idNumbers[x] == idNumbers) { cout<<"User #"<<x + 1<<"s ID Number = User #"<<i + 1<<"'s ID Number."<<endl; cout<<"Enter user #"<<i + 1<<"'s number again "; cin>>idNumbers; isIdentical = 1; } else isIdentical = 0; } } } for(x = 0; x < MAX; ++x) { cout<<idNumbers[x]<<endl; } getch(); } Excuse the bit of disorderliness. If anybody could help, that would be great. :)

All right. I'm sorry about this. Maybe I could just leave this be then... I actually got pointed in the right direction from other sources, so I no longer need assistance. Sorry for my newbiness. :p
