Array Addition using Class Function in C++

This is a C++ program that adds two matrices using a class named Add. Here's how the program works:

The program prompts the user to enter the number of rows and columns for the matrices.
The program creates an object of the Add class, and calls the sum method of the object, passing the number of rows and columns as arguments.
The sum method creates three 2D arrays: m1, m2, and s. m1 and m2 are used to store the two matrices entered by the user, and s is used to store the sum of the two matrices.
The program prompts the user to enter the elements of the first matrix row by row, and stores the values in the m1 array.
The program prompts the user to enter the elements of the second matrix row by row, and stores the values in the m2 array.
The sum method adds the corresponding elements of m1 and m2 to create s.
Finally, the sum method prints out the elements of s as a single row, with each element separated by a space.

Overall, this program performs the same function as the previous program, but uses object-oriented programming to encapsulate the matrix addition functionality in a class. One potential improvement to the program would be to add error handling in case the user enters invalid inputs, such as non-numeric values or matrices with different dimensions.

{
  public:
    void sum(int r,int c)
    {
      int m1[r][c],m2[r][c],s[r][c];
      cout<<"\nEnter the elements of  First matrix: ";
      for(int i=0;i<r;i++)
      {
        for (int j=0;j<c;j++)
        {
          cin>>m1[i][j];
        }
      }
      cout<<"\nEnter the elements of Second matrix: ";
      for(int i=0;i<r;i++)
      {
        for(int j=0;j<c;j++)
        {

      }
      cout<<"Output: ";
      for (int i=0;i<r;i++)
      {
        for (int j=0;j<c;j++)
        {
           s[i][j]=m1[i][j]+m2[i][j];
           cout<<s[i][j]<<" ";
        }
      }
    }
};
int main()
{
  int row,col;
  cout<<"\nEnter the number of rows: ";
  cin>>row;
  cout<<"\nEnter the number of column: ";
  cin>>col;
  Add obj;
  obj.sum(row, col);
  return 0;
