Question

Write a program of addition of two matrices using array

Answer 1

#include <stdio.h>

int main()

{

int m, n, c, d, first[10][10], second[10][10], sum[10][10];

printf("Enter the number of rows and columns of matrix\n");

scanf("%d%d", &m, &n);

printf("Enter the elements of first matrix\n");

for (c = 0; c < m; c++)

for (d = 0; d < n; d++)

scanf("%d", &first[c][d]);

printf("Enter the elements of second matrix\n");

for (c = 0; c < m; c++)

for (d = 0 ; d < n; d++)

scanf("%d", &second[c][d]);

printf("Sum of entered matrices:-\n");

for (c = 0; c < m; c++) {

for (d = 0 ; d < n; d++) {

sum[c][d] = first[c][d] + second[c][d];

printf("%d\t", sum[c][d]);

}

printf("\n");

}

return 0;

}

Answer 2

Answer:

public class MatrixAdditionExample{  

public static void main(String args[]){  

//creating two matrices    

int a[][]={{1,3,4},{2,4,3},{3,4,5}};    

int b[][]={{1,3,4},{2,4,3},{1,2,4}};    

   

//creating another matrix to store the sum of two matrices    

int c[][]=new int[3][3];  //3 rows and 3 columns  

   

//adding and printing addition of 2 matrices    

for(int i=0;i<3;i++){    

for(int j=0;j<3;j++){    

c[i][j]=a[i][j]+b[i][j];    //use - for subtraction  

System.out.print(c[i][j]+" ");    

}    

System.out.println();//new line    

}    

}}
