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.
The C programming language is a general programming language. It can be used to program anything, like computers, embedded systems, operating systems and computer applications. It is a structured and procedural programming language. In the beginning it was developed for UNIX, for system development but due to its ease of use and simplicity it has been used for application development. It is now being used at almost any computer platform and operating system. It is an excellent programming language for due to its simplicity of expression, the compactness of the code, and the wide range of applicability.
Quicksort is a well-known sorting algorithm developed by C.A.R. Hoare: Quicksort. QuickSort is an efficient algorithm based on Divide and Conquer rule and is still a commonly used algorithm for sorting. It works by selecting a ‘pivot’ element from the array and partitioning the other elements into two sub-arrays and recursively sorting them.
TrueEncrypt is a free open Source Encryption Software written in C++ programming language. If you haven’t used TrueCrypt before but need to protect confidential information and documents then I can totally propose to use this Free Software. The latest version has the ability to encrypt the whole drive on windows operating system. So without the password (which you set to encrypt the drive), you can not run your windows operating system.
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.
