dynamic variables help

need help with the first part to enter the name and display it
when i enter a name nothing happens

Code:

---


#include <iostream>
using namespace std;

const int MAXNAME = 10;

int main()

{
  int pos;
  char * name;
  int * one;
  int * two;
  int * three;
  int result;

  one = new int;//  Fill in code to allocate the integer variable one here
  two = new int;//  Fill in code to allocate the integer variable two here
  three= new int;//  Fill in code to allocate the integer variable three here
  name = new char [MAXNAME];//  Fill in code to allocate the character array pointed by name
 

  cout << "Enter your last name with exactly 10 characters." << endl;
  cout << "If your name has < 10 characters, repeat last letter. " << endl
                << "Blanks at the end do not count." << endl;
 
  for ( pos = 0;  pos < MAXNAME;  pos++)

          cin >> name;//name[MAXNAME];// Fill in code to read a character into the name array
            // WITHOUT USING a bracketed subscript

  cout << "Hi ";
  for ( pos = 0;  pos < MAXNAME;  pos++)

      cout <<  &name;// Fill in code to a print a character from the name array
              // WITHOUT USING a bracketed subscript
 
 
 
 
 
  cout << endl << "Enter three integer numbers separated by blanks" << endl;

 
  int *ptr1= one;
  int *ptr2= two;
  int *ptr3= three;

  cin >>  *one >> *two >> *three;// Fill in code to input three numbers and store them in the
  // dynamic variables pointed to by pointers one, two, and three.
  // You are working only with pointer variables

  //echo print
  cout << "The three numbers are " << endl;

  cout <<  *ptr1 << endl; 
  cout <<  *ptr2 << endl;
  cout <<  *ptr3 << endl;// Fill in code to output those numbers

  result = *one + *two + *three;// Fill in code to calculate the sum of the three numbers
  cout << "The sum of the three values is " << result << endl;

  delete one;// Fill in code to deallocate one, two, three and name
  delete two;
  delete three;
  delete name;

  return 0;
}

So what does "WITHOUT USING a bracketed subscript" allow you to do?

Is replacing
ptr[i]
with
*(ptr+i)
allowed?

Why are you going crazy with new? There is no need for new here. Is there a special reason you use it?

yes its allowed, but i cannot figure this name array part out at all

So if you had just
char name[MAX];

without any of the dynamic allocation, would you know what to do?

If so, you already have the answer - dynamic allocation doesn't change how you solve the problem in this case.

lol if you know the limit of your the string length why use DMA?
use DMA only when necessary..make your life and other programmers easier
