C program to add rows and columns of matrix

C program to add rows and columns of matrix

Output:

Enter the elements of array:
1 2 3
4 5 6
7 8 9
Row wise sum:
         The sum of row 0 is 6
         The sum of row 1 is 15
         The sum of row 2 is 24
Column wise sum:
         The sum of column 0 is 12
         The sum of column 1 is 15
         The sum of column 2 is 18

Implementation:

#include <stdio.h> #define r 3 //update row size here #define c 3 //update column size here int main(void) { int a[r][c]; int i,j,sum=0; printf("Enter the elements of array:\n"); for(i=0;i<r;i++) { for(j=0;j<c;j++) { scanf("%d",&a[i][j]); } } printf("Row wise sum:\n"); for(i=0;i<r;i++) { for(j=0;j<c;j++) { sum+=a[i][j]; } printf("\tThe sum of row %d is %d\n",i,sum); sum=0; } printf("Column wise sum:\n"); for(j=0;j<c;j++) { for(i=0;i<r;i++) { sum+=a[i][j]; } printf("\tThe sum of column %d is %d\n",j,sum); sum=0; } return 0; }
