sure
You mean read from file/standard input? With function fgets.
'dat' isn't common for extension for imagyes; but read/fread still usable
I am guessing you typed the question wrong, the way I understand your question is "Why is the programming language named C++ and not C ? " The answer to this is that there is a programming language called C, and in that programming language the ++ means increment by one. So C++ is the language C improved, as such it can read and compile all C programs in addition to having other features that C does not have.
to write and read the values
The getchar() is used in 'C' programming language because it can read the character from the Standard input(i.e..from the user keyboard),and converts in to the ASCII value.
In UNIX: use function chmod
open, read/write, close
We can read and write to files with the help of file commands in c programming.There are so many commands related to file for read,write,append,delete etc.
To learn sign language a site is ok but it is MUCH better to be taught as you have to interact with sign and read the response which is in a mirror image when you look at others
