In this post, we will study how to perform matrix multiplication using pointers in two ways – without using recursion and using recursion.
In this article, we will learn different ways to sort a two dimensional (2D) array. Sort all elements of a 2D Array In this section, we discuss how to sort all the elements of the 2D array such that all the elements in a row are in increasing order and the first element of any …
In this article, we will learn how to find the minimum number of comparisons to find the minimum and maximum elements of an array and derive a general formula for it. The formula for the minimum number of comparisons to find the minimum and the maximum elements is ( 3n / 2 ) – 2 …

Initialize 2D array C++ to zero. Set all elements of a 2D array to 0 using memset. How to initialize a 2D array with all zeros in C++?
Merge Two Sorted Arrays into one sorted array using Recursion. Merging sorted arrays using recursion is similar to merging using a loop.
In this article, we will discuss how to declare Matrix in C++. We will use array to represent Matrix. A Matrix is nothing but a 2-D array. We can declare Matrix in C++ in 2 ways Static Allocation Dynamic Allocation Declare a Matrix in C++ (Static Allocation) Static Allocation means memory is fixed. The memory …
Write a Program to Subtract 2 Matrices in C. Program for the subtraction of two Matrices in C using recursion and without using recursion.
The main difference between array and the linked list is that array occupies contiguous memory whereas linked list memory is scattered.
