When we delete a pointer, the object it points to will be deleted. However, this does not happen when pointer objects are stored in an STL container.

Using profiler to analyze the performance of code is more efficient, detailed, and intuitive than pure cognitive analysis.

In C++, when the operand types of an operator are inconsistent, these operands will be converted to the same type. Type conversion is divided into implicit conversion and explicit conversion.

When designing classes to overload operators, it is essential to choose whether to implement the operator as a member or as a regular non-member function.
