Thread: random generators

I wanted to generate a floating point random number and i read about the functions drand48, erand48, are these functions paired and are analogous to the functions srand & rand.

i wrote the following program

Code:

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

int main(void)
{
	int i;
	int number;
	float random_value;
	float float_number;

	printf("What is the number");
	scanf("%d",&number);


	drand48((unsigned int)time(NULL));

	for(i=0;i<10;i++)
	{
		random_value=erand48(); 
		float_number=random_value/(float)number;
		printf("\n%f",float_number);
	}




	getch();
	return 0;
}

but got the following errors
