Thread: another little program: is this correct?

Hello,
I am experimenting with random numbers and guessing games, this is my attempt.
It works for me, can someone give some better solution to the program?

Thanks in advance.

Code:

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

int main(void)
{
	int randno, guess, test, count, high, low;

	randno = guess = test = count = high = low = 0;

	{
		time_t t = time(NULL);
		while (t > 0u - 1 + 0.0) 
			t = t / 2;
		srand(t);
		printf("Il random seed e' %d\n", t);
	}

	randno = (rand()%100000)+1;
	printf("Il numero da indovinare e': %d\n", randno);

	count = 1;
	high = 100000;
	low = 0;

	test = (high+low)/2;

	printf("Il numero provato e' %d.\n", test);

	while(test != randno)
	{
		if(test > randno)
			high = test;
		else
			low = test;
		test = (high+low)/2;
		printf("Il numero provato e' %d.\n", test);
	}
	return 0;
}
