First you need to understand that what is programming language before understanding c.the programming language is used for communcitating with computer we used programing programming language as a medium.

C is a programming language used for communicating with computer.it is also a  high level language used for developing operating system.

C language it is procedural language used for creating command line applications.

C is procedural language.it follows structural and top down approach to solve any problem.while consider c++ is a object oriented programming language.it follows objects and bottom up approach to solve any problem.c++ is discovered using by c basic syntax.c++ has lot more features that c doesn,t have.c++ have all important features that c have.
