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 »

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 »
