## Introduction

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

#include <stdio.h> #define size 3 // Defining Matrix size int main() { int Arr[size][size]; int row, col, sum = 0; //Inputing elements in matrix from user printf("Enter elements in matrix of size %dx%d: \n", size, size); for(row=0; row<size; row++) { for(col=0; col<size; col++) { scanf("%d", &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 printf("Sum of elements of row %d = %d\n", row+1, sum); } // 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 printf("Sum of elements of column %d = %d\n", row+1, sum); } return 0; }
