How can I learn C programming language?

Steps Learn about C++’s history. The best way to start programming a language is to learn its roots. Install a C++ compiler (and possible IDE). A compiler is required for programming in C++, because the actual source code has to be compiled into a file that your computer can run. Choose a tutorial or two to start learning C++.

What is a preprocessor in C programming?

The C preprocessor or cpp is the macro preprocessor for the C and C++ computer programming languages. The preprocessor provides the ability for the inclusion of header files, macro expansions, conditional compilation, and line control. In many C implementations, it is a separate program invoked by the compiler as the first part of translation.
