Sum of Each Column of a Matrix
Sum of Each Column of a Matrix: Program: import java.util.Scanner; public class MatrixColumnSum { public static void main(String[] args) { int r, c; Scanner s = new Scanner(System.in); r = s.nextInt(); c = s.nextInt(); int[][] matrix = new int[r][c]; for(int i = 0; i<r; i++) { for(int j = 0; j<c;j++) { matrix[i][j] = s.nextInt(); } } int sum = 0; for(int j = 0; j<c; j++) { sum = 0; for(int i = 0;i<r; i++) { sum += matrix[i][j]; } System.out.println(j+1 + " " + "Column sum is: " + ""+ sum); } } } Output : 3 3 1 2 3 4 5 6 7 8 9 1 Column sum is: 12 2 Column sum is: 15 3 Column sum is: 18 Happy Coding 💻:-)
