Your nested **for** loop on line 15 IS looping five times.

I'm not sure about this one, maybe you could have a pointer to some dynamically allocated memory?

>Question 5 What is the meaning of the word 'const', and give one good reason why it is good to declare a const variable for the size of an array? The word **"const"** is short for constant, and really all this does is ask the compiler to keep an eye …

[QUOTE=bleedi;1782916]Hey guys! I've got a small problem that I can't figure out.

Print out the first number and also store it in an array. Get the second number and compare it to the array, and if not found in the array, store in array and print out, else don't print out. Loop around and do again for each additional number.

[QUOTE=Raisefamous;1782953]Hi, I need to sort a string of symbols and numbers in to two different strings, first one with numbers, second with symbols.

There are two things going on here - sorting the input in ascending order, and then counting the number of integers in a line. So first off, you need a sorting algorithm to sort each line in ascending order. There are various sorting algorithms that you could use which you …

[QUOTE=while(!success);1780916]Hey guys, learning about multi-dimensional arrays and am tracing a code that my teacher gave us, but I'm failing to see or conceptualize it. for instance: Why does the following code output 3?

It would be nice if you could improve the formatting when a message is being posted. What you post in the message box (editor) does not always come out on the board the same way. For example, if I include many spaces, like this: Hello how are you? then the …

On line 21, why are you assigning year2 the value of 1?

On line 86, the parameter list doesn't match the parameter list of the prototype.

Just think of the postfix operator (x++) this way: After everything is done and calculated on that line, [I][B]then[/B][/I] that variable is incremented just before leaving that line of code. For the prefix operator (++x), the variable x is incremented at the same moment that the compiler looks at it.

Run length encoding is simple, but it may not be suitable for your type of data. But it may work if you can deal with your data as a continuous string of ones and zeros and then compress the ones and zeros. After you uncompress the continuous string of ones …

[QUOTE=radiat;1759946]Hi, can you have a quick look at the two for loops here. I've declared the int 'i' in the first for loop but in the second for loop it doesn't recognise it and i have to declare it again. Why is that? [CODE]for(int i=0; i<x; i++) { cout << …

Well, you probably never would have solved this unless you asked. So it does matter.

Who ever said that enums and structures are supposed to make the code shorter??

[QUOTE=Vastor;1718593]in the 2nd code, the [B]int i[/B] is not defined in the main(), so, because of that, we can use multiple 'for loops' with same iterator([B]int i[/B])?[/quote] Yes you can, at least according to the C\C++ standard, but some compilers will allow the iterator to remain in scope even outside …

One easy way to do this is to use a bubble sort to sort the array in reverse order, then print out the array. A bubble sort is not very efficient, but it is easy and it will get the job done. Here is how a bubble sort works: Fill …

I would think that "locale_facets.tcc" also uses two variables called a and b. Try changing a and b in Main.h to something else and see if that corrects the problem.
