>pop quiz:: how many bytes in 64 bits?
Nice trick question, I might use it to trip up some of my friends

The answer is 8 btw.
64bits / 8bits = 8bytes
but I'm sure a bunch of other people answered before I saw this post.

>with any variable type why am I always getting 0?
Assuming that you haven't assigned a zero value to the variable, the reason is probably because it's global and you haven't assigned it a value yet. All global variables are initialized to the zero equivalent of that type automatically.

ok thx for the help

now i have another littlke problem

Code:

#include <iostream.h>

int main()

{
	double mass;
	cout<<"Enter the mass in kg: ";
	cin>>mass;
	cout<<"This mass would produce "<<(mass*300000000*300000000)<<" Joules of energy."<<endl;
	cout<<"It could power "<<((mass*300000000*300000000)/360000)<<" 100-watt light bulbs for an hour."<<endl;
	return (0);
}

enter mass 0.01
should produce 9e+14
light 2.5e+09 light bulbs

so now my problem is my output is in this form... 9e+014 and 2.5e+009 so why am i getting that so many zeros i only want 9e+14 and 2.5e+09

make them float variables
