How arrange names alphabetically?

Hello:

I have a txt file of many names, they arranged randomly. Say they are:
XYZ
ACD
ABC
OPQ
RST

Now I want to re-arrange them alphabetically as:

ABC
ACD
OPQ
RST
XYZ

How to do this, please! --Zhao

Insert them into std::set (elements are stored sorted) and then iterate through its elements.

What you're looking for is called "sorting".

Hi: Not using the sort skill before, I don't know how to start.
Could you tell me something more?

A quick search turns up this as a possible starting point.

See how you go with adapting the information there to what you have.
In your next post, be sure to include some code showing the definition of the struct or type of data that you are sorting.
