producing random numbers???

I have to produce a random number and can't figure it out. It gives me the same number each time. This isn't the homework. She told us how to produce the random number and i can't figure it out. The program I am writing for class is to learn how to use if statements.

I'm supposed to call srand once with a large prime number: srand(2707). Then it goes on to say that when you call srand with time as seed: srand(time(NULL)) the seed and the number will be different each time you run the program.

Here is the code that I have:

#include <iostream.h>
#include <iomanip.h>
#include <fstream.h>
#include <stdlib.h>
#include <time.h>

// I was told to include these three, should MAX_NUMBER be float?
void srand( unsigned int seed );
int rand ( void );
const float MAX_NUMBER = 20.0;
//

int main()
{
int number;

srand ( time( NULL ));

//I was also told to include this one.
number = int((float(rand() ) / float( RAND_MAX )) * MAX_NUMBER );
//
cout << number << endl;


system("PAUSE");
return 0;
}

got it to work!!

Use this code it will work i ganantee it

#include <stdlib.h>

int main()
{
randomize();
int RandomNumber = random(10); // Will display random number from 0-9

YOUR CODE

return(0);
}

If this doenst word your stdlib.h is corrupted

My stdlib.h has no function named random(); or randomize();
