cout help!

Okay so I am new to c++ and have a quick question. After looking at the code below I don't understand how to print x to 17.00. I know they are sticky flags I keep using them to demonstrate but why does the 2nd or 3rd line of code not produce 17.00 they produce the output below the code. HELP!!!!

Code:

#include <iostream>
#include <iomanip>

int main(void)
{
	double x = 17;

	std::cout << x << std::endl;
	std::cout << std::setprecision(2) << x << std::endl;
	std::cout << std::showpoint << std::setprecision(2) << x << std::endl;
	std::cout << std::noshowpoint << std::setprecision(2) << x << std::endl;

	return 0;
}

Code:

17
17
17.
17

You've only told it to use as much precision as it needs so long as it only needs two or less.

If you want a fixed format you should probably read the documentation.
