nasty bug help

learningcplusplus898 (33)
I have a nasty bug in this piece of code not sure how to fix it.
I'm focused on the first part not the part where I return values(have not started to change that yet)

I enter in data and then select 3 times ether 'year' 'month' or 'day'
the way year month or day is selected will be the output of the data.
so if selected order was year month day then output would be "year month day" in that order. but I'm not sure how to do this so I've decided to use an array to store the order of what is selected..

other function will catch the value of 13 ( if selected was "year month day" )
and print data.

BUT!!! after you select the first 2 their counters are both '1' so when you select the third the place in array will be changed.

The while loop on line 38 is rather strange. Does it compile? What is it supposed to do?

if you want the index of the array in selectedDay/selectedMonth/selectedYear you need to assign the index i. I.e. on line 46 selectedDay = i; and similar for line 89/132.

still get same problem
this is output "

1
2
3
4
5
6
7
 
year
element in array 0 is now 3
Day
element in array 1 is now 2
month
element in array 1 is now 3


for the while loop on line 38 it does compile.it is suppose to exit when user has selected day year or month atleast once, each time day/year/month is selected it makes it true, if user selects month/day/month then month is set to false due to the "if else " statements.

thanks for response.

just thinking if I add the I counter in somewhere.

do you think thing would work well?

	if( dayCoutner == 1 && i == 1 )
	{
	        cout << "elemet in array 1 is now 1";
	        formatPrint[1] = '1';
	}
	if( dayCoutner == 1 && i == 2 )
	{
		cout << "elemet in array 1 is now 1";
		formatPrint[1] = '1';
	}


if I where to do this then then the code itself will be a lot longer.

It looks like that dayCoutner/monthCounter/yearCounter exists so that the user cannot enter day/month/year twice, correct?

Do not use this counter for anything else. There is no array 0/1/2 only one: formatPrint.


I'm not sure what the use of formatPrint is, but i bet that it correspond with selectedDay/selectedMonth/selectedYear (not ...Counter).

I'd expect somthing like this:
1
2
3
4
5
6
7
8
9
10
 
				case 'd':
				case 'D':
...
						formatPrint[selectedDay] = '1';
...
				case 'm':
				case 'M':
...
						formatPrint[selectedMonth] = '2';
...


The while loop on line 38 is ignored. It does nothing. You might move the condition to line 34.
