Where would a good place be to learn more about multithreading? I don't think there is much at www.cpluplus.com. Any suggestions on libraries/tutorials? Thanks!

You need to put the return 0; at the end of your main() function. The padBlanks() function will return the string.

I believe what you're looking for would be the ASCII character codes (http://www.asciitable.com/).

Ah yes I see! That would explain my confusion. Sorry i missed it!

What kind of factorial is this? An input of 3 will result in an output of 6... it should be 3 * 1. If you enter 4 you will get something like 24. Factorials break numbers down like this: 12 factorial...

Try posting an attempt. You may want to store the input in an array and then sum the elements of the array with a loop. counting the numbers will be the next step. Post the sumation code first.

If you change the numbers[] array so the first element stored is the length of the array, then you can eliminate the second variable and simply keep passing the array to the function.

You can loop through a string and find the '/0' though, correct?

If you want to use modulo without floating points try (int)myFloat % (int)myOtherFloat

Perhaps opening and closing the string for the box causes a 'return' to be placed on it each time. Then, when you open the string again, the stream starts at the end of the string, which would cause...

Your explanation is very thorough. If you want to read more about the concepts you could try http://en.wikipedia.org/wiki/Object-oriented_programming.

Can't a literal constant also be defined as const float pi = 3.14159265358979323?

The error makes it sound like you're trying to redefine the function in your main file. You need to declare an instance of a class to use the functions in it.
