Subtract Two Matrices in C++

To subtract two matrices in C++ Programming, you have to ask to the user to enter the two 3*3 matrix elements, then start subtracting the matrices i.e., subtract matrix second from matrix first like mat1[0][0]-mat2[0][0], mat1[1][1]-mat2[1][1], and so on. Store the result in the third matrix say mat3[0][0], mat3[1][1], and so on. And after subtracting the matrices, print the subtraction result on the output screen as shown here in the following program.

C++ Programming Code to Subtract Two Matrices

Following C++ program ask to the user to enter any two 3*3 array elements to subtract them i.e., Matrix1 - Matrix2, then display the subtracted result of the two matrices (Matrix3) on the screen:

/* C++ Program - Subtract Two Matrices */
		
#include<iostream.h>
#include<conio.h>
void main()
{
	clrscr();
	int arr1[3][3], arr2[3][3], arr3[3][3], sub, i, j;
	cout<<"Enter 3*3 Array 1 Elements : ";
	for(i=0; i<3; i++)
	{
		for(j=0; j<3; j++)
		{
			cin>>arr1[i][j];
		}
	}
	cout<<"Enter 3*3 Array 2 Elements : ";
	for(i=0; i<3; i++)
	{
		for(j=0; j<3; j++)
		{
			cin>>arr2[i][j];
		}
	}
	cout<<"Subtracting array (array1-array2) ... \n";
	for(i=0; i<3; i++)
	{
		for(j=0; j<3; j++)
		{
			arr3[i][j]=arr1[i][j]-arr2[i][j];
		}
	}
	cout<<"Result of Array1 - Array2 is :\n";
	for(i=0; i<3; i++)
	{
		for(j=0; j<3; j++)
		{
			cout<<arr3[i][j]<<" ";
		}
		cout<<"\n";
	}
	getch();
}

When the above C++ program is compile and executed, it will produce the following result:
