Attention: The assignment Raii object must replicate the resources it manages, so the copy behavior of the resource determines the copy behavior of the Raii object. General and common RAII copy behavior is: Suppress the copy, the

1. Knowledge points(1) sizeof is a single-head operation, not a function that gets the number of bytes in the memory space that the operand occupies.(2) The operand of sizeof can make the type name, or it can be an expression, if the type name is

Remember: To prevent resource leaks, use the Raii object, which obtains resources in the constructor and frees the resources in the destructor. The two commonly used RAII classes are tr1::shared_ptr and auto_ptr respectively. The former
