I'm trying to use Eclipse with C++, MinGW compiler, to debug some really simple programs, but i can't find a way to make it work, whenever i input a variable by keyboard, it changes it to a random 40-50 number.

It's probably because of my lack of knowledge but my classmates were having trouble aswell so i wanted to make sure we were doing it 'right'.

@John3136: It's an `int`, not a `char`. – Christian Hackl Feb 19 '17 at 21:47

Is it still random if you initialize `i` to `0`? Is the breakpoint on line 39? What happens if you put it on line 40? – Dan Mašek Feb 19 '17 at 21:50

does cout print the correct int (3)? I'm guessing line 39 hasnt been run yet. – Erix Feb 19 '17 at 21:50
@Erix If i execute it normally, it works just fine, ut just gives troubles on debug mode – DSN94 Feb 19 '17 at 21:55
@DanMašek Yeah, but not instead of 49-51, it goes to 60-70 – DSN94 Feb 19 '17 at 21:59
@DanMašek And nothing changes if i put the breakpoint on line 40 – DSN94 Feb 19 '17 at 22:00
