 if ( z == 1 )
		{
			
	    add Num;
		Num.getNum(x,y);
		
		cout << Num.addition();
		
	         }
		
	    if ( z == 2)
	        {
	    	Multiplication Numbers;
		Numbers.getNum(x,y);
		
	    	cout << Numbers.multiply();
	    	
		}

cout << "Please enter one or two : ";

do
{
		if ( z == 1 )
		{
			
	    add Num;
		Num.getNum(x,y);
		
		cout << Num.addition();
		
	         }
		
	    else if ( z == 2)
	    {
	    	Multiplication Numbers;
		Numbers.getNum(x,y);
		
	    	cout << Numbers.multiply();
	    	
		}
		else {
			cout << "Please enter one or two : ";
			//Here is the problem
	}
} while(z != 1 && z != 2);

No, I have a psychotic hatred for constructs like these:

} while(z != 1 && z != 2);

Better with a switch:

1
2
3
4
5
6

9
10
11
12
13
14

bool valid = false;

while (!valid) {
  switch (z) {

    case 1:
       valid = true;  // after this case is executed, code continues after the while loop
       // your code here, consider making it a function 
       
       break;
    case 2:
       valid = true;
       // your code here
       break;
     default:
        std::cout << "Please enter 1 or 2\n"; 

  }
}


Look at the tutorial:
