C++ Program to Add Two Matrices (Multi-dimensional Array)

In this tutorial, we will learn about the addition of matrices. i.e. a program to add two matrices using a multi-dimensional array in C++.

Quick Info:💡

↪ As we know, what is a multidimensional array and how to display multidimensional array (matrices) in C++?

↪ Here, we’ll try to find out the sum of matrices using C++ programming language.

↪ Steps to perform above task:

• First, input the two identity matrices.
• Second, perform the addition of two matrices i.e. C[][]=A[][]+B[][].
• Third, display the result on the output screen.

Program to Add Two Matrices (Multi-dimensional Array)

Here’s a direct method to add two matrices in multidimensional array.

Simply, the user will be asked to enter two identity matrices then, the sum is computed and displayed to the user.

Example:

#include<iostream.h>
#include<conio.h>
void main()
{
int i,j,A[2][2],B[2][2],C[2][2];
cout<<"Enter the elements of array:"<<endl;
for(i=0;i<2;i++){
for(j=0;j<2;j++){
cout<<"Enter the elements of A["<<i<<"]["<<j<<"]:";
cin>>A[i][j];
}}
cout<<"Enter the elements of array:"<<endl;
for(i=0;i<2;i++){
for(j=0;j<2;j++){
cout<<"Enter the elements of B["<<i<<"]["<<j<<"]:";
cin>>B[i][j];
}}
cout<<"Matrix A[][] is:"<<endl;
for(i=0;i<2;i++){
for(j=0;j<2;j++){
cout<<A[i][j]<<"\t";
}
cout<<"\n";
}
cout<<"Matrix B[][] is:"<<endl;
for(i=0;i<2;i++){
for(j=0;j<2;j++){
cout<<B[i][j]<<"\t";
}
cout<<"\n";
}
cout<<"Sum of matrices is:"<<endl;
for(i=0;i<2;i++){
for(j=0;j<2;j++){
C[i][j]=A[i][j]+B[i][j];
cout<<C[i][j]<<"\t";
}
cout<<"\n";
}
getch();
}
