PLEASE HELP sort object vector

coiseng (12)
Hi, I'm newbie with C++ and I found an example which I need http://ideone.com/Eikbr4

But I've a question, how do I seperate this piece of code into .h and .cpp..

I tried to do something similar on my own but I'm having struggling with it after multiple try.. I've read many sort article on the but it's just not help..

missionplan.h

You're going along the right lines. But why do you have all those global variables? Why do they need to be global?

Also, you can't define a function inside a method like you're trying to do with that sortByCiv() function.
