I am just now learning about user defined functions and i want to right a function that, when given a number such as 1234, will display the number as 1,234.
I have no idea where to start with this so some help would be appreciated. I know you can't just give code, so if you could lead me in the right direction to start that'd be great.
Thanks
How do you know where a coma goes?

I know that it's every three numbers, but i have no idea how to take three numbers out of a group and print a comma in between
Here are some hints/leading questions to help get you started:
*What data type does your comma-containing number need to be? (hint: a comma is not a numerical character)
*Given an array of decimal digits, do you need to scan it from the front or the back to decide where the commas go?
Code:while(!asleep) { sheep++; }
Worry about each part separately. How do you take 3 numbers off of a larger number? Break everything down into small steps using words, then try to figure out how that would be a line of code once you have all the steps down.Originally Posted by 337higgin

There is a "high" level way to do this. You let your program know your locale, and printf() can format it appropriately. Unfortunately, I didn't know about that, and always worked it out, the "low" level way.
I remember a thread on this board (quite a while back), where we did almost nothing but this very thing - must have had 6 different ways of doing it, including bit masking. Search the forum and you should find it.
Oddly, it's a clever logic exercise, all on it's own. Worth exploring.
