I have to create a program that has user defined functions in it. The functions should be able to do the following. Uppercase the first letter of a string. Upper case every new first letter of a string, uppercase case every letter of a string. And upper case every letter after a period, exclamation or question mark. All of these need to be there own individual function.
Here is the catch. Only using a iostream library. Any ideas where I would start or how to create something like this? Would I have to use the ascii table? Thank you!
