Calculate the SUM

This C Language program reads a sequence of positive integers from the console, given by the user, and prints them out together with their sum. Use a Sentinel value (say 0) to determine when the sequence has terminated. So wehenever the user will enter 0 the program...

Copying One File to another in C

This is a simple C program that copies the contents of one file onto another file. It is similar to Unix’s cp  command. This C program is called with two parameters i.e. the names of two files. The contents of the file referenced in second parameter are copied onto the file which is referenced by first parameter. 

Borland C/C++ compiler Interface

This is a Borland C/C++ compiler Interface using the graphics.h library. This program uses many functions of graphics.h library provided by C Language. like line(), setcolor(), outtextxy() etc… You can play around with this code to learn how to make simple and...

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.
