You need to learn how to call a function (among many other things). Back up in your text a bit. [edit]Call [inlinecode]srand[/inlinecode] only once in your program, before you call [inlinecode]rand[/inlinecode]. Use [inlinecode]rand[/inlinecode] to obtain a random number between 0 and [inlinecode]RAND_MAX[/inlinecode]. If you want to narrow the range, a …

Again, be careful with array sizes.[QUOTE=atrusmre] [CODE] for (int i = 0, i <= 2, i++) m_cPeople.AddString( (LPCTSTR)names[i]); [/CODE][/QUOTE]This loop executes 3 times and tries to write from three strings.

A struct cannot contain an instance of itself -- perhaps you meant to have a pointer to the next instance in the Node (and elsewhere).

Focus your attention here in [inlinecode]deleteNode[/inlinecode]: [code] if(current->info == deleteItem) { trailCurrent = current->back; trailCurrent->next = current->next; if(current->next != NULL) current->next->back = trailCurrent; if(current == last) last = trailCurrent; count--; delete current; }[/code]

[QUOTE=smallville]I was able to get that step down using the bubble sort - my problem now is that I need to use arrays and modular programming to get this code to work properly.[/QUOTE]Why not a [inlinecode]std::vector[/inlinecode] and other standard functions such as [inlinecode]std::sort[/inlinecode]? And you may have missed [post=155265]this[/post]. [edit]Oh, …

You've just discovered your first reason to dislike global variables! [code]balance = (Interest + 1.0f) * [COLOR=Magenta]B[/COLOR]alance;[/code]

Something similar to this? [CODE]#include <iostream> using namespace std; int main() { cout << "Press [enter] to continue..."; cin.get(); cout << "Hello\n"; return 0; }[/CODE]

[QUOTE=wdowell84]One of the problems I'm having is that it keeps saying that local function definitions are illegal.

Perhaps it means that you intermingle [inlinecode]hat_size[/inlinecode] as both the name of a variable and a function and the compiler is trying to figure out which one you mean in any particular context. You tell it a couple things and expect it to know which one you mean.

And you may want to break out of the loop when you find an answer.

Did you type two characters -- [inlinecode]'A'[/inlinecode] and a newline? Also, [inlinecode]getchar[/inlinecode] returns an [inlinecode]int[/inlinecode].

First, consider a real code editor instead of something like MS Word that capitalizes unwantedly and automatically. C and C++ are case sensitive. And I'm sure there must be plenty of good, and free, code editors available. Second, it's a bad idea to use [inlinecode]eof()[/inlinecode] to control a loop. Check …

[url]http://www.parashift.com/c++-faq-lite/misc-technical-issues.html#faq-39.2[/url] But that's probably not applicable. I'd probably look at [inlinecode]s[0][/inlinecode] to see if there is a [inlinecode]'-'[/inlinecode] there. This may look cute or high-tech or something when you're new: [code]j = s[i] - 48;[/code] But later on you'll find out it's better to write it like this. [code]j = …

I'd guess that you intended this: [code]if (current > highest)[COLOR=Magenta];[/COLOR][/code]to be this:[code]if (current > highest)[COLOR=Blue]{[/COLOR][/code]

If you had an array of at least two of the objects, and you took the address of adjacent elements, cast each address to a [inlinecode]char*[/inlinecode], and found the difference between each address, you would have the size of one object.

This:[code]while(f=fgetc(c)!=EOF)[/code] is equivalent to this: [code]while(f=[COLOR=Magenta]([/COLOR]fgetc(c)!=EOF[COLOR=Magenta])[/COLOR])[/code]But what you want is this:[code]while([COLOR=Blue]([/COLOR]f=fgetc(c)[COLOR=Blue])[/COLOR]!=EOF)[/code]And you likely meant for [inlinecode]f[/inlinecode] to be [inlinecode]c[/inlinecode]. And [inlinecode]c[/inlinecode] should be an [inlinecode]int[/inlinecode]. And [inlinecode]main[/inlinecode] returns an [inlinecode]int[/inlinecode].

I think you use manipulators to set a width and zero fill. [code]#include <iostream> [COLOR=Blue]#include <iomanip>[/COLOR] using namespace std; int main() { int mint; cout << "Enter minutes: "; cin >> mint; int hh , mm; hh = mint / 60; mm = mint % 60; cout << [COLOR=Blue]setw(2) << …

Seed the random number generator only once in your program. Move your srand call to main, before your for loops.

Your function [inlinecode]isFactor[/inlinecode] expects two arguments, but you only pass it one.[code]if ( isFactor ([COLOR=Magenta]num1%2==0[/COLOR]) )[COLOR=Magenta];[/COLOR][/code]The trailing semicolon is likely extraneous and problematic as well.

This is not a valid format specifier:[code]scanf ("%[COLOR=Red].2[/COLOR]f", &number_gallons);[/code]Just use %f. Don't use this:[code]void main(void )[/code]The function main should return an int. This is undefined:[code]fflush (stdin); [/code]Try never to use it.

You can't return arrays in C or C++. Nor can you copy arrays using assignment [edit]use strcpy to copy strings[/edit]. Is there some reason you aren't using [B]std::string[/B]?

[QUOTE=sunnypalsingh][code] system("pause");[/code][/QUOTE]Don't step backwards from correct and portable code to something that isn't. (And you forgot to #include the header that declares system() as well.)

A do...while looks like this:[code]do { /* do stuff */ } while ( /* your condition */ );[/code]And the semicolon at the end is important.
