I'm trying to write an echo like thing doing this
:

> echo Muffins
Muffinst
> echo two muffins
two muffins

The problem Is that the program isn't being started from command line,
The > is my programs input prompt (trying to write a very simple command line)
How would I do this?
Would it be possible with formatted input (cin>>)?
or would I have to use scanf?

Use getline()

How wOuld I separate echo from the rest of the string (seperatre not remove I still need to see what the person is doing)?

Write a couple test programs to understand how input works.

1) use cin in a loop to read and display what is read
2) use getline() in a loop to read and display what is read
3) same with other input commands you know
