Constructor & Destructor Documentation

Array::Array (  int    arraySize = 10 )

Definition at line 12 of file ArrayInt.cpp. { size = ( arraySize > 0 ? arraySize : 10 ); ptr = new int[ size ]; // create space for array assert( ptr != 0 ); // terminate if memory not allocated ++arrayCount; // count one more object for ( int i = 0; i < size; i++ ) ptr[ i ] = 0; // initialize array }

Array::Array (  const Array &    init )

Definition at line 25 of file ArrayInt.cpp. : size( init.size ) { ptr = new int[ size ]; // create space for array assert( ptr != 0 ); // terminate if memory not allocated ++arrayCount; // count one more object for ( int i = 0; i < size; i++ ) ptr[ i ] = init.ptr[ i ]; // copy init into object }

Array::~Array (    )

Definition at line 36 of file ArrayInt.cpp. { delete [] ptr; // reclaim space for array --arrayCount; // one fewer objects }
