What do you mean by having a username made of numbers? Do you want a text username that gets encrypted into numbers?

a username that combines number like nhez12 and password like nhez12 like that

Well you can use the string type. The string type can hold pretty much every character that is on the standard us keyboard.

#include <string>
#include <iostream>

using namespace std;

int main()
    string username, password;
    cout << "Please enter a username: ";
    cin >> username;
    cout << "Please enter a password: ":
    cin >> password;
    cin.ignore(80, '\n');  // clear input buffer

    cout << "Username: " << username << endl;
    cout << "Password: " << password << endl;
    cin.get();  // pause program

    return 0;

If you know hashing, you can create a simple hash function which takes username and some "key", hashes them to give you a unique password for that username. Here is a nice tutorial on hashing.
