Can someone check my program?

I'm missing something really easy but I can't figure out what.

The identifiers are not picking up.

Code:

---

#include "stdafx.h"
#include "stdlib.h"
#include <iostream>
#include <cmath>
#include <iomanip>
#include <cstdlib>
#include <ctime>

using namespace std;

int id;
int age;
long phone;
long creditcard;

int main()
{
cout << "Please enter Customer ID (0-49): " <<endl;

if (id > 49&& id <0)
{
cout << "ERROR: Please enter Customer ID (0-49): " << endl;
}
fill_values (age, phone, creditcard);
securitypreference (security);

if (security == 0)
{
print_secure (id, age);
}

else
{
print_all (id, age, phone, creditcard);
}

}

void fill_values()
{
srand(time(0));
age = (rand() % 40) + 20;
phone = (rand() % 8999999) + 1000000;
creditcard = (rand() % 8999) + 1000;
}

int security_preference()
{
srand(time(0));
security = (rand() % 2);
return security;
}

void print_secure(id,age)
{
srand(time(0));
cout << id << endl;
cout << age << endl;
}

void print_all(id, age, phone, creditcard)
{
cout << id << endl;
cout << age << endl;
cout << phone << endl;
cout << creditcard << endl;
}

I'm getting the following errors:

So, sufoode, do you think our OP learned anything by your post? Or do you think he just copied/pasted, without understand why what you did works?

he only changed a couple of sections of the code and it's not like the program was completed because of it. I did understand the changes he made although there was no explanation. I just needed some help trying to figure out what was wrong.

So, do you know why he did what he did? Or will you be back the next time you get similar errors?

HINT: function prototyping

May I point out, in sufoode's post, the full variable names are not in the function prototypes? While I realize they are not required, it is perhaps a good idea to put them in, to avoid some confusion, especially with editors that parse prototypes to enable auto-completion.

Besides that, I concur with rags_to_riches. Simply posting a solution is not a good idea, as the OP does not necessarily learn as much that way.

It is interesting that you have declared your variables as global and yet you pass them as arguments to functions?
