#include <stdio.h>

int main()

printf("Please Enter the %d elements of second matrix\n",m*n);

for (i = 0; i < m; i++)
for (j = 0 ; j < n; j++)
scanf("%d", &matrix2[i][j]);

printf("Subtraction Result of the two matrices is as follows:\n");

for (i = 0; i < m; i++) {
for (j = 0 ; j < n; j++) {
subtraction[i][j] = matrix1[i][j] - matrix2[i][j];
printf("%d\t", subtraction[i][j]);
}
printf("\n");
}

return 0;
}
```

Output

Enter the number of rows and columns of matrix
2
2
Please Enter 4 elements of first matrix
10
23
11
70
Please Enter the 4 elements of second matrix
1
4
7
3
Subtraction Result of the two matrices is as follows:
9         19
4         67

We can subtract two matrices, if they are both of the same order. That is they have same number of rows and columns.

We cannot subtract two matrices with different dimentions.
