## Introduction

I have used CodeBlocks compiler for debugging purpose. But you can use any C++ programming language compiler as per your availability.

#include <iostream> using namespace std; int main() { int r, c, a[100][100], b[100][100], sum[100][100], i, j; cout<<"Enter number of rows (between 1 and 100): "; cin>>r; cout<<"Enter number of columns (between 1 and 100): "; cin>>c; cout<<"\nEnter elements of First matrix:\n"; for(i=0; i<r; ++i) for(j=0; j<c; ++j) { cout<<"Enter element a"<<i+1<<j+1<<": "; cin>>a[i][j]; } cout<<"Enter elements of Second matrix:\n"; for(i=0; i<r; ++i) for(j=0; j<c; ++j) { cout<<"Enter element a"<<i+1<<j+1<<": "; cin>>b[i][j]; } // Adding Two matrices for(i=0;i<r;++i) for(j=0;j<c;++j) { sum[i][j]=a[i][j]+b[i][j]; } // Displaying the result cout<<"\nSum of two matrix is: \n\n"; for(i=0;i<r;++i) for(j=0;j<c;++j) { cout<<"\t"<<sum[i][j]; if(j==c-1) { cout<<"\n\n"; } } return 0; }
