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.

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)
All problems in computer science can be solved by another level of indirection,
except for the problem of too many layers of indirection.

But in my college it's very very veryyyyyyyyy old compiler its turbo borland c++ 3.0 and in that this method is not supported
Hey i got the reason i have to write cin.ignore() to clear the buffer it works!!
Tell your college to upgrade and stop teaching students nonsense with old compilers!
