C Program to compare two integer arrays

This C program compares two distinct arrays and if the arrays are same then content results in FALSE. The behavior of comparison is explained when we note that the comparison is a comparison of addresses, not contents....

Finding the Prime number in C

A prime number is a number greater than 1 that cannot be formed by multiplying two smaller natural numbers. A natural number greater than 1 that is not prime is called a composite number.

C Program to Add Sequence of Numbers

This C program reads a sequence of positive integers as input by the user and print their sum. The program keeps on taking the input from user until user enters number ( 0 ) and program calculates the sum of all input numbers. Finally this C program prints the sum of all the numbers on screen and terminates.

Pointer to a Function

An example of using a pointer to a function. It must be pointed out that there is nothing new here, the pointer to a function is available in ANSI-C as well as in C++ and works in the manner described here for both languages. It is not regularly used by most C...

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. 

Enumerated type variable

Example that uses an enumerated type variable. This example uses enumerated type is used in C++ in exactly the same way it was used in ANSI-C with one small exception, the keyword enum is not required to be used again when defining a variable of that type, but it can...

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.
