## Introduction

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

#include <iostream> #define size 3 // Defining Matrix size using namespace std; int main() { int Arr[size][size]; int row, col, sum = 0; //Inputing elements in matrix from user cout<<"Enter elements in matrix of size "<<size<<" x "<<size<<"\n"; for(row=0; row<size; row++) { for(col=0; col<size; col++) { cin>>Arr[row][col]; } } // Calculating sum of elements of each row of matrix for(row=0; row<size; row++) { sum = 0; for(col=0; col<size; col++) { sum += Arr[row][col]; } //Printing Sum of row elements cout<<"Sum of elements of row "<<row+1<<" = "<<sum<<"\n"; } // Finding sum of elements of each columns of matrix for(row=0; row<size; row++) { sum = 0; for(col=0; col<size; col++) { sum += Arr[col][row]; } //Printing Sum of columns elements cout<<"Sum of elements of column "<<row+1<<" = "<<sum<<"\n"; } return 0; }
