Problem with rand()

[taj79]

Hi,

Code: Select all

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


main()
{
	int i,j;

	for(j=0;j<10;j++)
	{
		i = rand();
		printf("\n%d",i);
	}
}

I am running this in Microsoft Visual C++.
The problem is I am getting same set of values everytime I run ... what should I do to get different sets of value ?

Hi. You must use the srand() function to set the random seed (read more about this in help pages or google). to get random numbers you should use srand(time(NULL)), with #include <time.h>, this will give different numbers for different moments of execution.
You should also read about using higher bits for better randomization.
