Compilers and interpreters are themselves

ANS:C - Programs

Computer is Full of Programs.

Program by which we can play songs, movies and can manage our data.

But there are some programs which allow us to command computer(write programs) like:- C, C++, Java, php.

This commands are more close to human language. Like Print ("hello"). or Go to: Last.

We need a special software which can convert this commands to machine language(means 0's and 1's).

And the Compiler and Interpreter are the same program which convert high level language to machine level language.
