Generating Random Number in C/C++

C Standard Library provides two different methods to generate random numbers. They are: rand() and srand().

C Algorithms Library

This article is about a collection of common Computer Science algorithms which may be used in C projects. The C Programming Language has a much smaller Standard Library as compared to other more modern programming languages such as Java or Python. The library provides a basic set of mathematical functions, string manipulation, type conversions, and file and console-based I/O.

The “Hello, World!” Program in C

This is a simple “Hello, World!” C program to display "Hello, World!" text on the computer screen or display device. Typically, the best way to learn programming is by writing code. The first program beginners write is “Hello, World!” which is often used to illustrate...

C Implementation of Base64 Encoding and Decoding

Base64 encoding and decoding schemes are commonly used to encode binary data. Normally this is required when textual data needs to be transferred over the network or similar media and make sure that data is transferred without any modification. Base64 is commonly used in a number of applications, including email via MIME, and storing complex data in XML. This is a very simple implementation of base64 encoding and decoding in C programming language. There are number of C libraries available for encoding and decoding as well i.e. libb64, OpenSSL Base64, Apple’s Implementations, arduino-base64 etc.

Kruskal’s Algorithm Implementation in C

This is the implementation of Kruskal’s Algorithm in C Programming Language. This algorithm is directly based on the generic MST (Minimum Spanning Tree) algorithm. Kruskal’s algorithm is a greedy algorithm in graph theory that finds a minimum spanning tree for a connected weighted graph. It finds a subset of the edges that forms a tree that includes every vertex, where the total weight of all the edges in the tree is minimized.

Porter’s Algorithm in C

Originally written in 1979 at Computer Laboratory, Cambridge (England), it was reprinted in 1997 in the book “Readings in Information Retrieval”. Initially it was written in BCPL language. Here is the list of implementations in other programming languages including C, Java and Pearl implementations done by author himself.

Reading Files

This is a small C language program that can read a text file. The program is given file name as command parameter and it reads the file line by line. The program will prints out number of characters and words in each line. The program will also prints out the number...

C++ Program to solve the Quadratic Equation

This program will solve quadratic equations. It accepts coefficients of a quadratic equation from the user i.e. a, b and c and displays the roots. To compile the program name it quadratic_solver.cpp then type g++ -o quadratic_solver quadratic_solver.cpp You may need to use math.h like this: #include if you are using windows C++ programming software. (I tried it without the math.h and got an “undeclared identifier” error)

C++ “Hello World” Program

Typically, the best way to learn programming is by writing code. The first program beginners write is “Hello, World!” which is often used to illustrate the syntax of a programming language. You can take a look at the list of Hello World Programs in 300 Programming Languages to see how “Hello, World!” looks like in different programming languages.

Add time using structures in C++

This is a C++ implementation of adding time using structures. A structure is a convenient tool for handling a group of logically related data items. Structure help to organize complex data is a more meaningful way. It is powerful concept that we may after need to use in our program Design.

Common Text Transformation Library

Common Text Transformation Library, CTTL for short, is a set of C++ classes and functions to understand and modify text data. The library implementation is based on STL classes and algorithms. The library provides components for creating lexical analyzers making...

C++ program to demonstrate Inheritance

This is a simple C++ Program to demonstrate Inheritance. Simpler methods in the classes have been changed to inline code to shorten the file considerably. In a practical programming situation, methods that are this short should be programmed inline since the actual code to return a simple value is shorter than the code required to send a message to a non-inline method.

C++ Program to demonstrate Function Name Overloading

This is a simple C++ Program to demonstrate Function Name Overloading. An example of function name overloading within a C++ class many_name is used in this program. The constructor is overloaded as well as one of the methods to illustrate what can be done in C++...
