是否有必要销毁char * =“string”或char * = new char [6] [英] Is there a need to destroy char * = "string" or char * = new char[6]

问题描述

我假设当 char * =string与 char * = new char [6] 。我相信这些字符串是创建在堆而不是堆栈。所以，当我使用它们或者他们被自己毁灭时，我需要销毁它们或释放它们的记忆。

I assume when I do char* = "string" is the same thing aschar* = new char[6]. I believe these strings are created on the heap instead of the stack. So do I need to destroy them or free their memory when I'm done using them or do they get destroyed by themselves.

推荐答案

否。你只需要手动分配内存时使用 malloc 函数（在C中）或 new 运算符（在C ++中）。如果你不使用 malloc 或 new ，那么 char * 或字符串将在堆栈上创建或作为编译时常量。

No. You only need to manually free strings when you manually allocate the memory yourself using the malloc function (in C) or the new operator (in C++). If you do not use malloc or new, then the char* or string will be created on the stack or as a compile-time constant.
