[QUOTE=new programer;1017463]Howdy Folks! I've been asked to write a program that reads in an interger N and calculates The factorial ... I wrote this yesterday but it does not seem to work .. here's the code : [CODE] #include <iostream> using namespace std; int main() { int i=0; int s=1; …

Any casting you do to get this to work will just be a band-aid to cover up a problem. This program doesn't need any casts. Lines 63 and 64 appear to me to be impossible to reach. Line 22 - season is uninitialized, but you use it in a comparison …

You don't need to copy anything to get a row. You just need a pointer. The program below reserves space for and initializes 12 integers. Row 2 is integer indexes 8 through 11. "Copying" implies changing the memory at certain locations. That isn't necessary here. The row2 array simply points …

Everyone has way less than before, except for newbies, who appear to have the same. I remember Ancient Dragon starting a thread requesting a way that he could possibly neg rep someone without placing them in an eternal red zone. Makes sense. Everyone deserves to make a mistake and learn …

Please repost the expected and actual output in code tags. All spacing gets stripped out otherwise so we don't know if that happened here. I suspect so because neither figure looks like a diamond. The expected output looks like a half-diamond. Is that what you want?

I've googled this and it looks to me like what I am trying to do is impossible. I'm trying to write a [ICODE]Display[/ICODE]function that can take different parameters and call the appropriate function based on those parameters (i.e. function overloading).

This isn't a code snippet, this isn't C++, get rid of the HTML code, and this is way too much code for someone to go through without a much more precise pinpointing of the problem by you. [LIST=1] [*]Post in the correct forum. [*]Post as a regular thread rather than …

There's more than one way of splitting it up. Here are two of them: [code=text] 1->2->3->4->5->6->7->8 becomes 1->2->3->4 and 5->6->7->8 or 1->3->5->7 and 2->4->6->8 [/code] The first way requires you to know how many elements you have in the first list before splitting the list. Go through half of them, …

Here's a code snippet I wrote a while back that you might find useful. It isn't the only way to do it, but it has a nested loop and takes advantage of some efficiencies such as not testing 4, 6, 8, ... as the previous poster mentions. Nor will it …

If you need help, then this isn't a code snippet. Please post as a regular thread.

You isolate a character int a string using the [] operator. [code] string input = "yes"; char firstLetter = input[0]; if (firstLetter == 'y' || firstLetter == 'Y' || firstLetter == 'n' || firstLetter = 'N') cout << "Input is valid\n"; else cout << "Input is invalid.\n";[/code]

I've never heard of "rt" mode. Are you sure you didn't intend the mode to be "r+"? Check errno and see what the problem is. Here's the man page for fopen. I see no "rt" option on it. It also has the possible error flags. [url]http://www.manpagez.com/man/3/fopen/[/url] But since you're using …

Since you haven't provided the printInfo function, we can't see whether anything is wrong with it. My first advice would be to just have printInfo () display "Hello World" and return. If you don't get that output, then it's not even being called and that narrows down your problem. If …

You call srand ONCE during each program, then you call rand to generate the numbers. If you want ten numbers, call srand (time(0)) once at the very beginning of the program, then call rand () ten times: [code] srand (time (0)); // first line of program for (int i = …

I'm not a Windows programmer, so I can't help debug, but is there anything in the program that requires you to use all of these Windows-specific headers? Will the regular C and C++ standard libraries not do what you need? I'm pretty sure nothing but Visual Studio uses "stdafx.h", and …

This isn't a code snippet. If possible, please change the thread type to a regular old thread as opposed to a code snippet. The && operator doesn't work that way. You want something like this: [code] if (a > b && a > c) cout << "First value is the …

In addition to post 2, you still have problems. I'm not entirely sure what they are, but if x1, x2, y1, y2, z1, and z2 are supposed to be the same values at the end of the first function as they are at the end of the second function, they …

The compiler doesn't like the fact that you are initializing this array between lines 10 and 47. It wants you to do the initialization after line 47. Is this a static array? If not, you may want to initialize it in the constructor. Anyway, check out this link. I don't …

There are a lot of problems with both the algorithm and the program's implementation of the algorithm. Let's start with primes[]. What should primes[] eventually contain if I enter a max of 25? Is primes[] supposed to contain all prime numbers less than 25? The first 25 prime numbers? Regardless, …

Sounds like there is a lot of math involved. If you refer to a theorem, you should link it: [url]http://en.wikipedia.org/wiki/Separating_axis_theorem[/url] Is this a math problem or a problem with the implementation of the math in Java (i.e. do you understand the theorem and know how to use it successfully, but …

One, it's [ICODE]int main ()[/ICODE], not [ICODE]void main ()[/ICODE]. Two, we need an input file. Three, what's the point of having a program with no output, either to the screen or to a file? How do you test it? If there is output, I missed it. Four, what's the question?

[QUOTE=vs49688;1007243]Hey, Does anybody know of a way to generate a random number without using srand(time(NULL)).

Try setting your Pawn panels to a background color of green or something and see if anything that's displayed ends up being that color. If it isn't displayed, it can't be clicked. You have this line: [code] new Pawn(); [/code] which creates Pawn objects, but these objects never get displayed? …

You need to post more code. We need to see the declaration of mGPA. Presumably it's a double, float, long, int, something like that, so when you enter "x", >> can't do anything with it and it has this "x" in the stream that it must get past before it …

Ancient Dragon already explained the way it works here in your last thread. Post some code (in code tags) that shows you've made an attempt, then ask a SPECIFIC question:

Your comment in line 7 is revealing. It says that the ending bracket ends the function isAlive (). It does not. It ends the if-else statement. You need ANOTHER ending bracket after that to end the isAlive () function. Right now you have your toString () function INSIDE of your …

Line 29 won't work. getline reads a line, so you should have this (no = sign): [code] getline (cin, line); [/code] If you then want to convert line into an integer, use atoi or strtol. These work on C-style strings, not C++ style strings, so convert line using c_str (); …

[QUOTE=whiteyoh;1005394]Hi All, I have an array of 3 objects stored in cdList.

Define "value". Your CD class doesn't have a data member called "value". It has "Cost". Is that "value"? If you're adding up all the Costs, you can have a static variable in your CD class. You can also have one for the number of CD's. Something like this: [code=JAVA] public …

Having a static Collection of CD objects is fine and will work, but I see nothing in your requirements that would need more than I posted in my post in your last thread (a static integer and a static double, adjusted during each call to the constructor). Did you run …

There are a few ways of calculating the standard deviation, some more efficient than others. Say you have five points: 1,2,3,4,5 Calculate the mean, which is 3. Now go through the points one at at time and get the differences: [code=text] 1 - 3 = -2 2 - 3 = …

One, use code tags: Two, what's the question? Three, don't use `void main ()` even if your compiler lets you get away with it. Use `int main ()`.

There isn't too much to a boolean function. They return true or false based on whatever. Here's an example of a boolean function that returns true if both numbers passed to it are the same, false if they are different. You'll need to change it to accept the parameters you …
