Sample Solution:

C Code:

#include <stdio.h>

void main()
{
  int arr1[50][50],brr1[50][50],crr1[50][50],i,j,n;
  
       printf("\n\nAddition of two Matrices :\n");
       printf("------------------------------\n");  
        printf("Input the size of the square matrix (less than 5): ");
       scanf("%d", &n); 
  
    /* Stored values into the array*/
       printf("Input elements in the first matrix :\n");
       for(i=0;i<n;i++)
        {
            for(j=0;j<n;j++)
            {
	           printf("element - [%d],[%d] : ",i,j);
	           scanf("%d",&arr1[i][j]);
            }
        }   
  
       printf("Input elements in the second matrix :\n");
