C Example Programs

The best way to learn C programming is by practicing lots of example programs. The benefit of practicing examples, besides learning concepts is improved problem-solving skills and coding skills.

Some programs in the list given below include flowchart to help you understand the program logic.

We highly recommend trying these examples on your own, before comparing the solutions.

Prerequisites

The prerequisites to learn and practice these examples listed below.

C Tutorial – learn C programming language before you practice example programs.
C Compiler – you will need a C compiler to run these example programs. Learn how to install Turbo C++ 3.0 compiler.
Pen and Paper – Some programs especially math related programs require you to verify the output manually.
