C program to make two matrix dynamically and show thier addition

int main()

   int row, colum, row_element, colum_element, first[50][50], second[50][50], sum[50][50];
   printf("Enter the number of rows and columns of matrix\n");
   scanf("%d%d", &row, &colum);
   if(row>0&&colum>0)
   {

}

output
