delete vs delete[] operators in C++(C++ 中的 delete vs delete[] 运算符)

问题描述

What is the difference between delete and delete[] operators in C++?

The delete operator deallocates memory and calls the destructor for a single object created with new.

The delete [] operator deallocates memory and calls destructors for an array of objects created with new [].

Using delete on a pointer returned by new [] or delete [] on a pointer returned by new results in undefined behavior.
