I am trying to write a code that will accept integers into a vector and then will take a number with more than 3 digits ex. "2431" and then use a class called commas to manipulate into "2,431" by adding the ','. My teacher gave me a power point to look at to help write my commas class but I am beyond confused. My main file is written correctly but I am having trouble w/ the commas class. Any help is appreciated. Also I have been reading more about user defined manipulators through various websites and am still a bit confused on how they function. If anyone knows a link that would further explain what user defined manipulators do / how they function and / or I am lookin for code that I can follow what I am tryin to implement here. Any help / suggestions is appreciated. Thank you.
