Store a value in an array

[zagzag]

Hi I am working on a program that asks the user to create an account and verifies if the account is already registered. I figured out that I can do this by storing the input value in an array. I was wondering if anyone can teach me how I can store an input value in an array and how to I verify if it was already entered. I hope I am not asking for too much.

First the variable is dependent on what you making it. Say if the user input is a 5 digit account number account.
First you have to declare how many account numbers there are. Without going into pointers and how create a dynamic array lets say there is only five people who have registered there account and we know there is only is only 5 people registered.

so....

 
int temp, count;  
int account [5]; //This declares the array with 5 spots.
int account [0] = 22134; // This declares the first number in the array to be 22134
cout << "Please insert account number."
cin >>  temp; 
for (count = 0; count < 5; count++) 
{
if (account [count] == temp) 
{
cout << "this is an account number"; 
} 
} 

Keep in mind this code isn't really what your trying to accomplish, but it kinda gives the idea of how to declare a static array, how put something inside of the array, and how to compare the values in a array with a different value. Furthermore, I would strongly suggest reading the c++ page on array's and checking out some tutorials on youtube. Here the page on arrays.

okay thanks a lot I got it ! i didn't know that u can save an account doing account [count] = temp;

I am not saving an account [count] but I am comparing the value in account[count] and temp. However, one could store the values in a for loop as well.
