c++ - C++ 中的 C 字符串删除

Question

什么是好的，什么是错的？在什么情况下我必须调用delete以防止内存泄漏？ 另外，C 和 C++ 中的行为完全相同吗？有什么区别吗？

const char* a = "blahblah";
...
delete a;

char b* = new char('a');
...
delete b;

char c[100] = "blahblah";
...
delete c;

char d* = new char[40];
...
delete d;

char e* = new char[40];
...
delete[] e;

Answer 1

In which case do I have to call delete in order to prevent memory leak

仅删除您从new获得的内容以及删除[]您从new []获得的内容。其他所有删除都是错误的。
