Question

Let A and B be the two matrix. The size of matrix A is m and size of matrix B. Then, find subtraction of C, is a A and B is defined as C(ij) = A(ij) - B(ij).

Answer 1

#include <stdio.h>

  
int main()  
{  
  int i, j,r,cl, A[10][10], B[10][10], C[10][10];  
  printf("Enter the number of rows and columns of matrix\n");  
  scanf("%d%d", & i, & j);  
  printf("Enter the elements of matrix A\n");  
  for (r = 0; r < i; r++){
    for (cl = 0; cl < j; cl++){
      scanf("%d", & A[r][cl]);
    }
  }  
      
  printf("Enter the elements of matrix B\n");  
   
  for (r = 0; r < i; r++) {
    for (cl = 0; cl <j; cl++){
      scanf("%d", & B[r][cl]); 
    }
