HI I KNOW I HAVE ASKED SO MUCH BUT PLEASE DO NOT IGNORE ME
I HAVE APART OF QUISTION THAT I COULDNOT COMPLETE IT
HERE IS IT
Then create an int specialization and in it add a function that returns the sum of all elements in the DoubleSubscriptedArray

HERE IS THE CODE I WANT TO ADD THIS FUNCTION TO IT

C++ Syntax (Toggle Plain Text) 
  1. #include<iostream.h>
  2.  
  3.  
  4. class DoubleSubscriptedArray{
  5.  
  6. 	int rows;
  7. 	int columns;
  8. 	int*ptr;
  9. public:
  10.  
  11. DoubleSubscriptedArray(){rows=1;columns=1;ptr=new int[5];}
  12. friend ostream &operator<<(ostream &stream,DoubleSubscriptedArray ob);
  13. friend istream &operator>>(istream &stream,DoubleSubscriptedArray &ob);
  14. int &operator()(int r,int c);
  15. int getr(){return rows;}
  16. int getc(){return columns;}
  17. DoubleSubscriptedArray operator=(DoubleSubscriptedArray ob);
  18.  
  19. };
  20. //---------------------------------------------------------------------//
  21.  
  22. int &DoubleSubscriptedArray::operator()(int r,int c){
  23. 	return ptr[(r-1)*c+(c-1)];
  24. }
  25. //---------------------------------------------------------------------//
  26. ostream &operator<<(ostream &stream,DoubleSubscriptedArray ob){
  27.  
  28. 	cout<<"The Array is: \n";
  29. 	for(int i=1;i<=(ob.rows*ob.columns);i++){
  30. 		cout<<ob.ptr[i-1]<<' ';
  31. 		int j=i%ob.columns;
  32. 		if(j==0)
  33. 		cout<<"\n";}
  34. 	return stream;
  35. }
  36. //--------------------------------------------------------------------//
  37. istream &operator>>(istream &stream,DoubleSubscriptedArray &ob){
  38. cout<<"Enter Number of Rows: \n";
  39. cin>>ob.rows;
  40. cout<<"\nEnter Number of Columns \n";
  41. cin>>ob.columns;
  42. delete []ob.ptr;
  43. ob.ptr=new int[ob.columns*ob.rows];
  44. for(int i=0;i<(ob.rows*ob.columns);i++){
  45. cout<<"Enter value of point number "<<i+1<<" ";
  46. cin>>ob.ptr[i];
  47. cout<<endl;}
  48. return stream;
  49. }
  50. //--------------------------------------------------------------------//
  51. DoubleSubscriptedArray 
  52. DoubleSubscriptedArray::operator=(DoubleSubscriptedArray ob){
  53.      for(int i=0;i<(ob.rows*ob.columns);i++){
  54. 		 ptr[i]=ob.ptr[i];}
  55. 	 return *this;
  56. }
  57. //--------------------------------------------------------------------//
  58. int main(){
  59. 	int x,y,z;
  60.   DoubleSubscriptedArray d,n;
  61.   cout<<"Please enter Info of first object \n";
  62.   cin>>d;
  63.   cout<<"Please enter Info of second object \n";
  64.   cin>>n;
  65.   cout<<"The first object is:\n";
  66.   cout<<d;
  67.   cout<<"Enter the coordinates of point in first object:\n";
  68. cout<<"row number: ";
  69.   cin>>x;
  70.   cout<<"\ncolumn Number: ";
  71.   cin>>y;
  72.   if((x>0&&x<=d.getr())&&(y>0&&y<=d.getc())){
  73. 	cout<<"The value of this point is: \n";
  74. 	z=d(x,y);
  75.     cout<<z;
  76. 	cout<<endl;}
  77. 	else
  78. 		cout<<"Sorry numbers are wrong\n";
  79.  
  80.   cout<<"The second object is:\n";
  81.   cout<<n;
  82.  
  83. if((d.getr()==n.getr())&&(d.getc()==n.getc())){
  84. 	  cout<<"We can assignement objects \n";
  85. 	  n=d;
  86. 	  cout<<"The second object become\n";
  87.       cout<<d;}
  88.   else
  89. 	 { cout<<"Sorry we cant assignemet objects!!!\n";}
  90.  
  91. return 0;
  92. }

Depending on your needs and knowledge something along these lines might work. This is only a rough outline of one possible way to proceed. If it looks like something that might suffice, it's up to you to fill in the details.
C++ Syntax (Toggle Plain Text) 
  1. template <T>    //use templated class for a general case class
  2. class DblSSA  
  3. {
  4.    T ** internalArray;  //declare size of internalArray using dynamic memory in constructor
  5.    int r;
  6.    int c;
  7.   . 
  8.   .
  9.   .
  10. }
  11.  
  12. class IntDblSSSA  //int specialization of prior template class
  13. {
  14.    DblSSSa <int> idsa;   //object of templated class only allowing int as type
  15.    .
  16.    .  
  17.    .
  18.    int sumOfArrayElements()  //find sum of all elements
  19.    {
  20.      int sum = 0;  //initialize variable to zero
  21.      for each row
  22.        for each col
  23.            sum += given element of idsa.internalArray
  24.      return sum       
  25.    }
  26. }
  27.  
  28. int main()
  29.   IntDblSSSA idsssa;  //declare an object of desired type
  30.   int result = idsssa.sumOfArrayElements()
  31.   cout << result
