Answer 1

The last read operation in the first iteration of the loop is cin>>c. Now cin maintains an input buffer for all read operations and then copies data from this buffer. But this operation leaves a newline in the buffer, which is then interpreted by the cin.getline call, and the output is skipped.

To remove the issue, add this after cin>>c:

cin.ignore(numeric_limits<streamsize>(cin),'\n');

And include the header, <limits>

What this does is remove all characters till a newline, and after removing the newline, it stops.

Answer 2

Saurabh Tiwari The numeric_limits part is just to specify the size of the cin's buffer. You can use a smaller number, or even 1 for this case.

Answer 3
