Defensive Programming Techniques

Defensive Programming Techniques

This source code is from Thinking in C++, 2nd Edition, Volume 2, by Bruce Eckel & Chuck Allison. You can use Borland, G++ (For version 3 and above only), Microsoft (For C++ with .NET only) to compile and build this source code. Writing perfect software may be a daunting task for developers, but a few defensive techniques which are routinely applied can go a long way toward narrowing the gap between code and ideal. Defensive programming practices are often used where high availability of the application is required, safety if utmost concern, or security is needed for application to work.

The C programming language is a versatile and widely-used programming language which makes it an ideal starting point for novice programmers. Originally developed for UNIX system development, C has evolved to become a go-to language for a variety of applications, including embedded systems, operating systems, and general computer applications.

Quicksort in C

Quicksort Implementation in C

Quicksort is a widely used sorting algorithm known for its efficiency and simplicity. Developed by Tony Hoare in 1960, this sorting technique follows the “divide and conquer” paradigm which makes it a powerful tool for organizing data in ascending or descending order. Programmers find quicksort to be an excellent introduction to sorting algorithms due to its straightforward implementation and elegant design.

graphics.h Reference

Graphics Library (graphics.h) Reference (part 3)

In the previous two posts (Graphics Library Reference part 1 and part 2) I have discussed few important functions of graphics.h library in C Programming. As promised here is the sample C language program which will demonstrate the use of graphics functions using C language and draw some geometrical shapes on the console. If you have followed the previous two posts the you will not find the source code difficult to compile and execute. If you still experience any problems using the source code or compiling the code the please do let me know, and I will try to figure it out.

graphics.h Reference

Graphics Library (graphics.h) Reference (part 2)

In the previous post I discussed few important functions mostly used to initialize and destroy the graphics mode in DOS environment. Today I will discuss graphics functions to draw different shapes and lines. So here we go by starting the line function which is most important function in creating any graphics.

graphics.h Reference

Graphics Library (graphics.h) Reference (part 1)

Graphics programming in C Language is discussed rarely. Today I will discuss some important functions of graphics.h in C programming Language and in the next coming article I will make a simple program to demonstrate the use of graphics functions. This is the part one of the article which discuses the important graphics function to create and destroy the graphics environment. In part two I will show you different graphics functions to draw shapes. And in last part I will add a sample program to demonstrate the use of graphics.h library. So let’s start with the description of important functions and their use.
