I'm looking to find the sums and differences of large numbers inputed by the user. all numbers must by positive and whole and the first number must be larger than the second. I'm having a couple problems:
1) I'm currently using arrays and saving the input into a string. I think that, when copying the data from the string to the array, I need to have the numbers at the very end of the array. I think I found a good way but its not working...
248 results in 0.0029 seconds.

Reading from array into the file - with encoding ascii characters
Dear members,
I'm a newbie and I created a simple program, but I have one problem I can't deal with. I should work on Win CE.
Ok: I want this program to read 'array of arrays' and save encoded data into file.txt. Every 3 bytes from there should be encoded from ASCII (function below).
The biggest problem is with loop (or some other way to fix it) to read all array (without any skips).
Now it's like:... -

Comparison of two waveforms of audio files
Hi,
I am a VC++ developer and currently need help in comparing two audio files. Lets say I have two wave files and one of it is created using the other with some modifications like lowering the loudness etc.
Now, I have to compare these files and see if the modified one is almost copy of the original one, means, while creating the modified one, my application has unknowingly not distorted the file.

C++ constructor help!!
class description (MyString):
class defines a sequence of characters (similar to class string). The implementation must be as an array of characters that are dynamically allocated and resized as necessary. You must use a null character to terminate the string - just like C-strings are null terminated.
deafult constructor:
...Code:/// get_length(char *s) gets length of s before null character. buf is private

The peg solitaire is in a triangular shape. Consisting of 15 pegs.
I'm just curious as to how it is programmed and I'm starting to learn C++ on my own. So how would I do such a puzzle on C++?

scanf problems with strings and chars
Hi,
Im quite new to C++ and am trying to learn most of the commands.
So i wanted to make a Programm that has a normal mode and a non normal mode, kindof.
