Hello,
As we all know that cin alone is not able to take full sentence, it can take only single word. My problem is when i use cin.getline(s,20) the program runs and there's no error but when i try to take the input it doesn't take
Without taking any input it moves to the next instruction!
Please tell me why is this happening? i tried using fflush(stdin) but still the same problem is coming. Please help me out! :(
First, it's better to use std::getline instead.
Fflush(stdin) is wrong and undefined. Never use it.
And as for the question, the FAQ has an entry for that I think. Otherwise the board has a suggestion somewhere because it's a very frequently asked question.
No we do not know that.Quote:

We know that operator >> stops on the white space.
There are other functions, that could work with input stream and they do not stop on whitespace, instead you can specify the delimiter (end-line or point for example)
But in my college it's very very veryyyyyyyyy old compiler its turbo borland c++ 3.0 and in that this method is not supportedQuote:

Tell your college to upgrade and stop teaching students nonsense with old compilers! :)
