 | Well, yes, it is full of errors, and keep in mind that sometimes when something is full of errors, the part you are having a hard time with may NOT be the error. The function you are worried about seems fine to me save for one thing: [code] string Date::convertMonthNumberToString(int … |

| | Function call must match the function declaration. Your function takes two parameters: [code] void arrSelectSort(double*, int); [/code] so you need to give it a double* and an integer when you call it on line 84 (line 4 in most recent post): [code] arrSelectSort(array, size); [/code] Leave off the [ICODE]double*[/ICODE] and … |

| | Bubble sort is the simplest sort algorithm out there. Google "bubble sort", "bubble sort c++", "bubble sort c++ sample code", stuff like that, and you'll get plenty of sample code, all based on arrays. Here's a bunch of applets I made myself explaining the different sorts. I really need to … |
| | I don't see where you're doing any conversion. You say you're converting to decimal. Is there an integer variable that holds the decimal? you have temp, but I assume that's just a temporary variable. What holds the final decimal value? I also don't see any initialization of the bitset that …  |
| | I think I see the logic, but I'm not 100% sure. I see no reason why you are not placing the [ICODE]i++ [/ICODE] in your outer loop or why you would want it inside your inner loop. Your job, it seems to me, is to go through chrs[] a character … |
| | You should post a short, complete program, including the array display function, the read_list function, and the main function that calls both.

Frankly I think the first question … |

| | Wherever you need to set aside memory and you have no idea how much memory you'll need at compile time, you'll probably need a "new" command. Whenever you have a "new" command, you'll need a "delete" command somewhere. A decent rule of thumb, but definitely only a rule of thumb … |
 | As I mentioned in your last thread, you need to define what an "invalid" answer is and what a "valid" answer is. It looks like you have decided to use regular expressions to do this, which is a good idea, but again, you and only you can decide what's "valid" … |
