Thread: My if-else statements won't execute

So I'm trying to create a program that will advance a user-specified calendar date by a user-specified number of days. So I created a while loop that should run through my if-else statements to appropriately advance the date, but for some reason, none of the if-else statements execute.

numDays = the number of days by which the date should be advanced

day = current day of the month

Code:

int x; 
	while (x = 0, x <= numDays, x++){


		if (month == 1 && ((day + numDays) < 31)){

			day++;

		}
		else if (month == 1 && (day + numDays > 31) && (isLeapYear(year) == true) && (day + numDays <= 60))
		{

			month = 2;
			day = day - 31;

		}
		else if (month == 1 && (day + numDays > 31) && (isLeapYear(year) == false) && (day + numDays <= 59))
		{

			month = 2;
			day = day - 31;

		}
		else if (month == 2 && (day + numDays > 29) && (isLeapYear(year) == true) && (day + numDays <= 60)){

			month = 3;
			day = day - 29;

		}
		else if (month == 2 && (day + numDays > 28) && (isLeapYear(year) == false) && (day + numDays <= 59)){

			month = 3;
			day = day - 28;
		}
		else if (month == 3 && (day + numDays > 31) && (day + numDays <= 61)){

			month = 4;
			day = day - 31;

		}
		else if (month == 4 && (day + numDays > 30) && (day + numDays <= 61)){

			month = 5;
			day = day - 30;

		}
		else if (month == 5 && (day + numDays > 31) && (day + numDays <= 61)){

			month = 6;
			day = day - 31;

		}
		else if (month == 6 && (day + numDays > 30) && (day + numDays <= 61)){

			month = 7;
			day = day - 30;

		}
		else if (month == 7 && (day + numDays > 31) && (day + numDays <= 62)){

			month = 8;
			day = day - 31;

		}
		else if (month == 8 && (day + numDays > 31) && (day + numDays < 61)){

			month = 9;
			day = day - 31;

		}
		else if (month == 9 && (day + numDays > 30) && (day + numDays <= 61)){

			month = 10;
			day = day - 30;

		}
		else if (month == 10 && (day + numDays > 31) && (day + numDays <= 61)){

			month = 11;
			day = day - 31;

		}
		else if (month == 11 && (day + numDays > 30) && (day + numDays <= 61)){

			month = 12;
			day = day - 30;

		}
		else if (month == 12 && (day + numDays > 31) && (day + numDays <= 62)){

			month = 1;
			day = day - 31;
			year++;

		}
		else{

			day = day + 1;

		}



	}

I have compiled and run the program and when I enter a date, such as 1/4/2016, and I enter 4 for the number of days to advance, it doesn't advance the date at all. It stays at 1/4/2016. Could someone enlighten me on what I'm doing wrong that is causing my if-else statements to not work?

Any help that you could offer is greatly appreciated!

Oh good catch. Thank you for your help! I don't know why I didn't think of that.
