Once a stream has failed, it will stay failed until it is cleared, so if you were to take this approach, you'd have to clear the stream at the top of the loop.
...

There will be no looping. 1 will be accepted as input. 3556 will remain in the stream. id will be assigned to be '1', which in Acscii is 49. Your solution deals with illegal input just fine, but...

The stream will fail on line 37 if something that is not a digit or a minus sign (or possibly a decimal? Can't remember) is entered. Once the cin stream is in a failed state, if you do not clear...

There's MySQL, there's C++, and there's how to use MySQL from C++. I've used MySQL++ as a wrapper successfully to do this, but that was a while ago, so I don't remember the ins and outs. The first...

I'm not the one assuming. You're assuming that it was a professor who gave the code as a debugging exercise and that anyone reading your post would know that "fixed" meant that "it now compiles and...

I understand exactly what's going on here. I've been doing this for quite a while and I've dealt with lots of beginners and first-time posters. I'm not assuming I know what he wants. I have no idea...

UberJoker, don't be so judgmental. The original code definitely had some problems, but we've all seen much, much worse. And the code you posted still has lots of problems. It's "fixed" in that it...

If you don't get any of the lines that I added as cout statements, that means that they aren't being executed even once, so it's breaking somewhere, and very early.

One, if you are new to C++, I would suggest not using C-Strings at all for this. C-Strings require you to adjust the null terminator. Regular strings do not. You use both in this program. It's...

Line 72:


while((t!=9&&w==0)&&((t!=9)||((w==0))));


Even if it is correct, it definitely looks overly complex. Maybe this?


while (t < 9 && w == 0);

Again, use code tags. See post 2 for how. Code is hard to read otherwise.

You got rid of the k++ line, so now k is always 0. Accident? What is this program supposed to do? If you have a...

So ARRAY_SIZE is 25? 26? Is it defined somewhere? It's not listed here, and a lot of other stuff isn't listed either, so it's impossible to run and it's...

I formatted the code to make it easier to read and added a few lines - see "Added by VD" in comments. cin.get() pauses so you have time to read. Press the "Enter" key to move on. Delete later. ...

The posts got messed up somehow so you have some truncated code, two triangle.h files, and no virtual.cpp function. Please repost using code tags:

Here's the normal layout I use (changed as needed, but pretty standard):

Thinking about my earlier mention of "map", while I don't think that "map" would work for you here, I'm wondering whether multimap or perhaps something else from STL might be useful to you here. ...

My advice is to create both classes that I suggested:


class Merchandise
{
string product;
double price;
};

class GroupedMerchandise

I'd confirm this if I were you. Until you've verified that it will work on all compilers, assume that it won't. Maybe it does. I've never seen this. I've always set up a loop and gone through the...

That's an associative array. They exist in some languages (i.e. PHP), but they don't exist in C++. A "map" would be a C++ alternative to an associative array.
...

What on Earth does this post mean and what does it have to do with prime numbers?

I've never seen this syntax before:


char array[MAX_SIZE] = {};


Does that initialize all of the elements to zero? If so, I've just learned something new. I've never seen '\0' used to...

This function:


bool checkQuestion (bool boolAnswer)
{
if (boolAnswer)
return true;

return false;
}

The syntax highlighting is fine. The indentation boggles the mind. This is much more readable:


if (a == b)
{
// do stuff
}
else if (a == c)
{
// do other stuff

Lines 15 - 24 - This loop is a black hole. Once you get to line 23 the first time, if you get to it, you'll never get out. Well, you'll get out when you go through it MAX_SIZE times, so that's a...

You need a way to tell whether a string is a number or not. Define exactly what a "number" is (negatives, decimals, commas, just digits, etc.), then you can write a function to test a string. If...

"Voila! Syntax-highlighting!" isn't part of the code tag. niek_e is just excited by the power of code tags and decided to spread the enthusiasm. Feel free to replace "Voila! Syntax-highlighting!"...

You need to meet more C++ programmers then. Custom namespaces are all over the place, for good reason. I just debugged my own (very short) project. The culprit? I had several functions called...

You CAN "return" more than one value. "Return" is in quotes on purpose. Pass the row and column by reference (denoted by &).

You should post your updated code and explain exactly what your present problem is. You've made a lot of revisions, but no one knows what they are.

Stringstreams will work wonders here. Let the >> and << operators do all the parsing and type changing work for you.

"Simple", "efficient", "correct", and "not tedious" are different concepts. Your "easiest", most brain-dead method is to make 120 "if" statements, not taking advantage of the results of previous...

Five numbers can be ordered 5! or 120 ways. The no-brainer way of writing this code would thus be writing an if statement with 119 "else if" statements, one for each possible ordering. You should...

You have number declared as an integer, but you are treating it as a string. There is no "int" class, so you cannot use the dot operator as you do in line 17. Use an if statement instead of the...

There are two separate terms to think about: "size" and "capacity". "capacity" is the storage allotted to the array. "size" is the number of elements in the array THAT YOU CARE ABOUT. The main...

If you do not know the size ahead of time, you can use the MAXIMUM size to make sure you have now overflow. There is no maximum size for this. There's a maximum number of columns, but not a maximum...
