*Largest and Smallest Element of a Matrix*

Write a C++ Program to Find Largest and Smallest Element of a Matrix. Here’s simple Program to Find Largest and Smallest Element of a Matrix in C++ Programming Language.

*What is Matrix ?*

**Matrix representation** is a method used by a computer language to store matrices of more than one dimension in memory. C uses “Row Major”, which stores all the elements for a given row contiguously in memory.

*Two-dimensional Arrays : :*

The simplest form of multidimensional array is the two-dimensional array. A two-dimensional array is, in essence, a list of one-dimensional arrays. An m × n (read as m by n) order matrix is a set of numbers arranged in m rows and n columns.

To declare a two-dimensional integer array of size [x][y], you would write something as follows −

*type arrayName [ x ][ y ];*

Where **type** can be any valid C data type and **arrayName** will be a valid C identifier.

Below is the source code for C++ Program to Find Largest and Smallest Element of a Matrix which is successfully compiled and run on Windows System to produce desired output as shown below :
