I just added this to my DevC++ library yesterday seeing as how often i use it.

here you go.


Code:
#ifndef _RANDNUM_H_
#define _RANDNUM_H_

#include <ctime>
#include <cstdlib>

using namespace std;

int randnum(int lownum, int highnum)
{
srand((unsigned)time(0));
   
   return (rand()%(highnum+1)+lownum);

}

#endif
