Thread: Help Please

The program is supposed to be printing 21 different numbers that are randomly generated. Why am I getting the same number 21 times?
Using dev C++ compiler.

Code:

/*prints random numbers between 1 - 99*/


#include <stdio.h>
#include <stdlib.h>
#include <time.h>


#define MAXR 99;
#define MINR 2;




double random(void);


int main(void)
{
  
  double sides[7][3];
  double ran_num;
  int i, n;
  
  for(n=0;n<3;n++)
  {        
  for(i=0;i<7;i++)
     {            
     ran_num = random();
     sides[i][n] = ran_num++;
     }
  }
  
  for(n=0;n<3;n++)
  { 
     printf("\n\n") ;  
     for(i=0;i<7;i++)
     {
        printf("%.2f      ", sides[i][n]);
     }
  }
  
  system("PAUSE");    
  return 0;
}


double
random(void)
{
   srand(time(NULL));
   int r;
   r = rand()%MAXR + MINR;
   return(r);
}

Probably because you have srand() in your function. This function should be called once and only once, usually early in main().

That fixed it, thanks!
