# Subtract Two Matrices using array

Write a C++ Program to Subtract Two Matrices using array. Here’s simple Program to Subtract Two Matrices using array 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 Subtract Two Matrices using array which is successfully compiled and run on Windows System to produce desired output as shown below :

### SOURCE CODE : :

```/*  C++ Program to Subtract Two Matrices using array  */

#include<iostream>
using namespace std;

int main()
{

int arr1[5][5], arr2[5][5], arr3[5][5], sub, i, j,m,n;

cout<<"Enter size of matrix ( Max:5 ) :: ";
cin>>m;
cout<<"\nEnter Elements to Matrix A Below :: \n";

for(i=0;i<m;i++)
{
for(j=0;j<m;++j)
{
cout<<"\nEnter arr1["<<i<<"]["<<j<<"] Element :: ";
cin>>arr1[i][j];
}

}

cout<<"\nEnter Elements to Matrix B Below :: \n";

for(i=0;i<m;i++)
{
for(j=0;j<m;++j)
{
cout<<"\nEnter arr2["<<i<<"]["<<j<<"] Element :: ";
cin>>arr2[i][j];
}

}

cout<<"\nSubtracting Matrix ( A - B ) ..... \n";
for(i=0; i<m; i++)
{
for(j=0; j<m; j++)
{
arr3[i][j]=arr1[i][j]-arr2[i][j];
}
}

cout<<"\nAfter Subtraction, Matrix C is :: \n";

for (i = 0; i < m; ++i)
{
for (j = 0; j < m; ++j)
{
cout<<"\t"<<arr3[i][j];
}
printf("\n\n");
}

return 0;
}```

### OUTPUT : :

```/*  C++ Program to Subtract Two Matrices using array  */

Enter size of matrix ( Max:5 ) :: 3

Enter Elements to Matrix A Below ::

Enter arr1[0][0] Element :: 1

Enter arr1[0][1] Element :: 2

Enter arr1[0][2] Element :: 3

Enter arr1[1][0] Element :: 4

Enter arr1[1][1] Element :: 5

Enter arr1[1][2] Element :: 6

Enter arr1[2][0] Element :: 7

Enter arr1[2][1] Element :: 8

Enter arr1[2][2] Element :: 9

Enter Elements to Matrix B Below ::

Enter arr2[0][0] Element :: 9

Enter arr2[0][1] Element :: 8

Enter arr2[0][2] Element :: 7

Enter arr2[1][0] Element :: 6

Enter arr2[1][1] Element :: 5

Enter arr2[1][2] Element :: 4

Enter arr2[2][0] Element :: 3

Enter arr2[2][1] Element :: 2

Enter arr2[2][2] Element :: 1

Subtracting Matrix ( A - B ) .....

After Subtraction, Matrix C is ::
-8      -6      -4

-2      0       2

4       6       8

Process returned 0```

Above is the source code for C++ Program to Subtract Two Matrices using array which is successfully compiled and run on Windows System.The Output of the program is shown above .
