Thread: strange integer problem

hmm...I just finished an excercise were i'm using structs to get phone numbers from the user. But i noticed when you lead any one of the numbers (i mean area code, exchange, number) it ends up in a different number when it prints out. so i just tried something out.

Code:

#include <iostream.h>

int main()
	{
	int x;

	cin >> x;
	cout << x;
	return 0;
	}

so if i entered 015 it would print 13
when i enter 020 it prints 16
when i enter 010 it prints 8
why is this? thanks!
