Subtract of two matrices


Write a C Program for Subtraction of two matrices. Here’s simple Program to Subtract two matrices 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 for Subtraction of two matrices which is successfully compiled and run on Windows System to produce desired output as shown below :
