#include<iostream>
#include<conio.h>
using namespace std;
int main()
{
    char s[10];
    char ch;
    cin.get(s,10); // type abcd <enter>
    cout<<s;
    //Will leave line feed in buffer
    cin.get(ch); // removes line feed
    cout<<(int)ch; //will display 10 Ascii value of line feed

    cin.get(s,10); // Can read characters again
    cout<<s;
    getch(); // function in conio.h to read a single character w/o echoing
    return 0;
}

You can probably fix this by clearing any error state after the each getline().

A C++ program can have lots of errors. Having multiple errors in the same place can make identifying them very difficult.

The above code didn’t work as expected.

When I inserted “Avishee Patterson is a very nice boy.” for the first getline, it only printed “Avishee Pa” and two “new lines” and exited.

What’s the catch? Why didn’t it work?
Is it because, I have more than 11 characters?
Is there any more feasible reason for this?

Does a C++ Program error has exactly only one reason? I mean, does a C++ error depends only on one cause?

You need to tell tell the people that you need to include the header “iomanip” if people want to use setw(). Visual C++ 2005 express edition gives the error “identifier not found :’setw’”.

[ Thanks for the note. I updated the example. -Alex ]

while (true)
  cin.get(ch);

Note that this is actually an infinite loop, and thus probably not something you’d want to do in a non-sample program.

Similarly would you please explain in detail “while (cin >> ch)” – does it mean, as long as something can be successfully read from cin and it is successfully stored in ch?

More generally, it would be a big help if you could explain things used in loop (or if) conditions which aren’t straightforward expressions like i<5. I find them hard to follow or understand but I couldn’t find anything about those in your control flow tutorials. I know they’re meant to evaluate to true or false but I’m not sure how you evaluate some of those conditions, especially if they involve pointers or operators like << etc.

And even more generally, may I say that your site has been very useful in explaining the basics in a way that’s clear, practical and provides a solid foundation for the reader to build on and progress from. Thank you very much.

When all the characters you typed have been printed, the buffer is empty again and it will wait for you to enter more characters into it.
