QUESTION

Write a C program to find the sum of two matrices of order 2*2 using multidimensional arrays.

“TESTCASE_1”: “2 2\n12 22\n10 12\n2 2\n22 25\n23 9\n###—###SEPERATOR—###—\n34 47 \n33 21”, “TESTCASE_2”: “3 3\n1 2 3\n4 5 6\n7 8 9\n3 3\n1 2 3\n4 5 6\n7 8 9\n###—###SEPERATOR—###—\n2 4 6 \n8 10 12 \n14 16 18”, “TESTCASE_3”: “0\n###—###SEPERATOR—###—\n0”, “TESTCASE_4”: “0\n###—###SEPERATOR—###—\n0”, “TESTCASE_5”: “0\n###—###SEPERATOR—###—\n0

ANSWER

#include <stdio.h>
 
int main()
{
   int m, n,p,q, c, d, first[10][10], second[10][10], sum[10][10];

   scanf("%d %d", &m, &n);
   
 
   for (c = 0; c < m; c++)
      for (d = 0; d < n; d++)
         scanf("%d", &first[c][d]);
 scanf("%d %d", &p, &q);
   
 
   for (c = 0; c < p; c++)
      for (d = 0 ; d < q; d++)
         scanf("%d", &second[c][d]);
 
   
 
   for (c = 0; c < m; c++) {
      for (d = 0 ; d < n; d++) {
         sum[c][d] = first[c][d] + second[c][d];
         printf("%d ", sum[c][d]);
      }
      printf("\n");
   }
 
   return 0;
}
