random number
I was trying to produce random numbers to input as coordinates, but the random number keeps returning the same value for both x and y.

#include <iostream.h>
#include <time.h>
int random(int);
void main()
{
int x,y,max;
cin >> max;
x=random(max);
y=random(max);
cout << x << ' ' << y; // Keeps displaying the same value
}
int random(int max)
{
srand(time(0));
return rand()%max;
}

Am I misunderstanding some concept in random numbers?
Note: This wouldn't compile for me with your code. So I have modified it to be more platform friendly.

#include <iostream>
#include <time.h>
using namespace std;
int random(int);
int main() {
srand(time(0));
int x,y,max;
cout << "Input Max:";
cin >> max;
x=random(max);
y=random(max);
cout << x << ' ' << y; // Keeps displaying the same value
return 0;
}
int random(int max) {
return rand()%max;
}

yay it works. thanks for your help =D
the problem was the position of srand, now it only gets called once.
