Course Introduction
Programs for practice
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:
Source Code: Print Hello World
/* 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();
}
Output
Enter 3*3 Array 1 Elements :2 2 2 2 2 2 2 2 2
Enter 3*3 Array 2 Elements : 1 1 1 1 1 1 1 1 1
Subtracting array (array1-array2) ...
Result of Array1 - Array2 is :
1 1 1
1 1 1
1 1 1
