string manipulation, etc.

Ok, so i have to take this older program that i wrote and develop a new input style for it. the original type of input was just separate integers of input on separate lines. now, we have to have input on the order of:

{5,100, 5123}

and the like. the input must start with the curly brace, and the commas separate values. when we output the user's set, any number that would contain a comma must contain a comma. for example:

{5, 100, 5,123}

as per the previous input. this last part i can't figure out... how can you insert a comma as part of the output of values?

think / and %

to output like this {1,2,3}
do it
cout<<"{"<<arr[0]<<"," <<arr[1] etc. :)

well, we have to change the output of the number from

1000

to

1,000

like you would write it longhand with the commas as digit grouping separators

If you're only dealing with positive numbers less than a million, you could do something like this:

Code:

---

int num = 12345;
cout << num/1000 << ',' << num%1000;

---

The output there would be: 12,345

that will be a great part of the code for the positive numbers, but it also has to have a condition for negative numbers........ the valild input will be in the range +32999 to -32999 or something... i'll probably use that for the positive values if it's easier than the code for negative values.

one problem with that little piece of code......... if the remainder portion has leading zeros, it won't display them. if you have 1000, i will display 1,. if you have 1002 it will display 1,2. i'll try to find a way around that myself for now though. ya know, so i can "further my education" and whatnot
