Why Array Indexing Starts with 0 in C?

Why array indexing starts with 0 in C, C++, Java and most of other programming languages is one of the common confusion among programmers. In this article I will tell you the reason behind it. Image Source Why Array Indexing Starts with 0 in C? Lets try to understand this by taking one example in… Read More »

C and C++ Program to Find Inverse of a Matrix

Here you will get C and C++ program to find inverse of a matrix. We can obtain matrix inverse by following method. First calculate deteminant of matrix. Then calculate adjoint of given matrix. Adjoint can be obtained by taking transpose of cofactor matrix of given square matrix. Finally multiply 1/deteminant by adjoint to get inverse.… Read More »

Program for Shell Sort in C and C++

Here you will get program for shell sort in C and C++. Shell short is an improved and efficient version of insertion sort. In this algorithm we sort the pair of elements that are far apart by gap h. The process is repeated by reducing h until it becomes 1. Program for Shell Sort in… Read More »

C/C++ Program for Union of Two Arrays

Here you will get C/C++ program to find union of two arrays. For example: First array: {1, 3, 7, 9} Second array: {1, 4, 6} Union: {1, 3, 4, 7, 6, 9}   C/C++ Program for Union of Two Arrays Union of Two Sorted Arrays If two arrays are sorted then their union can be… Read More »

C/C++ Program to Remove Duplicate Elements From Array

Here you will get C and C++ program to remove duplicate elements from array.   For example: Given Array: 5 8 9 5 12 9 New Array: 5 8 9 12 In this program I have compared each element with all other elements. If the element is equal to any other element in the array then… Read More »

Anagram in C

Here is the program for anagram in c.   Two strings are said to be anagrams if by rearranging the characters of any one string will make both strings equal.   Example: “adssfa” and “dsasfa” are anagrams “adsfa” and “sdfac” are not anagrams How to Check two Strings are Anagrams or not? So what we will… Read More »

Insertion Sort in C & C++ – Program & Algorithm

In this tutorial I will explain about algorithm for insertion sort in C and C++ using program example. The insertion sort inserts each element in proper place. The strategy behind the insertion sort is similar to the process of sorting a pack of cards. You can take a card, move it to its location in sequence and move… Read More »

Selection Sort in C & C++ – Program & Algorithm

In this tutorial I will explain about algorithm for selection sort in C and C++ using program example.    One of the simplest techniques is a selection sort. As the name suggests, selection sort is the selection of an element and keeping it in sorted order. In selection sort, the strategy is to find the smallest number… Read More »
