measuring elapsed time

[metulburr]

using linux...

I tried numerous suggestions, mostly a version pertaining to :

#include <iostream>
#include <ctime>

int main() {
	clock_t begin = clock();

	while(1){
		clock_t end = clock();
		double elapsed_secs = double(end - begin) / CLOCKS_PER_SEC;
		std::cout << elapsed_secs << std::endl;
	}
}

What exactly is this suppose to be, as not one digit measures one second accurately?

The only code that i found that measures seconds accurately is:

#include <iostream>
#include <ctime>

int main2(){
	clock_t start, end;
	time(&start);
	while(1){
		time(&end);
		double dif = difftime(end,start);
		std::cout << "seconds: " << dif << std::endl;
	}
}

but the problem is it measures seconds as whole, as an int. There is no milliseconds, etc.
