Stuck! (easy problem)

Why doesnt this work?

Its giving me a headick!

Code:

---

#include <conio.h>
#include <cstdlib>
#include <iostream>
#include <stdio.h>
#include <time.h>

using namespace std;

double random_number;
double number_generator()
{
        srand( time(NULL) );
        random_number = rand()%10+1;
        return random_number;       
}

int main()
{
        cout << random_number;
        getch();
        return 0;
}

---

random_number is never defined in main();

before outputing it do: random_number = number_generator();

and seed rand in main as well.

edit:: follow one of the other suggestions as well and don't use global variables.

Ok. Do srand() at the top of main(), not in number_generator(). Next, you aren't ever calling number_generator(). That would be why random_number isn't getting a random number. Then, your 'random number' generator is trying to operate on a double, when rand() only deals with ints. And you shouldn't be using the global variable.

Code:

---

#include <iostream>
#include <ctime>
#include <conio.h>

using namespace std;

int number_generator()
{
        return rand()%10+1;
}

int main()
{
        srand(time(NULL));
        cout << number_generator();
        getch();
        return 0;
}

It's because your not actully calling the function try something like this

Code:

---


double number_generator()
{
  double random_number = rand()%10+1;//This does not need to be a global
  return random_number;
}

int main(void)
{
  srand(time(NULL)); 
  cout<<number_generator();//this will print out what number_generator returns
  return 0;
}

Thanks all. I'm new to c++ so it's really nice to have you guys here :).
