Dynamic allocation of memory

[kupiko]

Hello i'm working on problem of dynamic allocation of memory.
I would like to have variable char name[?] set in the way to be able to
change the memory it uses while program is running for ex. I will type
name Kupiko and i would like my variable name to be that large no more no
less. Not just to set the amount of char to name[20]. Please could anyone
advice me how to do it?

Yes. Look up "malloc" and "realloc" in the index of your C text book.

man 3 getline

Since when is that ISO C? Note that you have no idea what kind of system
the OP is on; it need not have POSIX (or whatever extension getline is)
at all.

It's not even POSIX, it's C++ for use with the std::string template
class.
