Hello world.
I'm talking about
reading in strings
from the user in C++
I have program here,
and I've included the string header file.
I've declared name as a string.
And I display a prompt
to the user that says "Enter your name:"
cin>>name
and then I output hello and whatever the name is.
Let's run this.
And I put in Robin
as my name,
and it says "Hello Robin"
It might be tempting to think
that everything is working great.
Let's run it again,
and this time going to
put in my name is Robin Banks.
And it says "Hello Robin"
So we can use just cin for the name.
What I'm going to use instead
is getline.
And getline takes
the input stream
that you want to read from,
and the variable you want to read in.
and that reads the whole line.
So let's run this again now
and I will put in Robin Banks again.
and it says "Hello Robin Banks"
So that's how you could read in a whole line
or something with a space in it.
One of the problems with
using cin is that
if we read in just Robin,
and the input buffer had "Robin Banks",
"Banks" is still in the input buffer,
and the next cin would try to read in "Banks"
and that's a problem.
and that's it for now.
