    while function

    i am trying to run the following while loop, but no matter what the input is, it keeps giving me the answer of "numb is 1".
    what am I doing wrong?

    Code:
    numb=0
    while (year<2009)
    		
    if((year%4==0 && year %100 !=0), year %400==0)	
    {numb=numb+1;
    year=year+1;}
    else 		
    {year=year+1;}
    		
    printf("Numb is %i\n\n",numb);

    Because you're using a comma "," when you mean or "||".

    While is not a function by the way. I'm not really sure what you would call it, but it definitely is not a function.

    Another note: always keep your code correctly indented. It would have been much easier to read your code if it was organized.

    	}

    }
    printf("Numb is %i\n\n",numb);
    I believe you are in serious need of learning how to use proper programming style. Please have a read:
