2.1    Storage Management

C++ defines two functions for storage management,
         new (for storage allocation)
         delete(for de-allocation).

The syntax for new is
              pointer = new <type> or
              pointer = new <type> [<size>]

new returns a pointer.
 Example:
                  int *pi = new int;                          // a pointer to a new int
                  Rational *p1 = new Rational;         // a pointer to a new Rational
                  Rational *p2 = new Rational[10];   // a pointer to an array of 10 Rationals
                  Rational *p3 = new Rational(3,4);  // pointer to new initialized Rational

QUESTION:
            What advantage(s) does new have over malloc or calloc?
 ANSWER:





De-allocation of storage is done by the function delete.

The syntax for delete is 
            delete <object> or
            delete [] <object>

For example:
                   delete pi;                // deletes the single int pointed to by pi
                   delete [] p2;             // deletes the entire array of Rationals


The private getBuffer function called by the constructors

inline void String::getBuffer(const unsigned int Max_Length)
{
     Buffer_Len = Max_Length + 1;
     Buffer = new char [ Buffer_Len ];
     if( !Buffer )
         Error( "Out of space" );
}
The function Error is not defined. You must write it.
