User-defined memory allocation

• Operator new: allocate memory from the heap pointerType* pointerName = new pointerType ; TimeStamp* ttsPtr = new TimeStamp;
• Operator delete: release allocated memory delete pointerName; delete ttsPtr;
• Commonly used with arrays in a similar way:
  pointerType* pointerName = new pointerType [size];
  double* positionVector = new double [3];
  delete [] pointerName ; delete [] positionVector;
• Improper user memory management causes the most difficult C++ bugs!!
