C++类成员变量初始化一次

[英]C++ class member variable initialize once

原文 2018-05-15 15:38:54 1 1 c++

I am looking for a way to make sure a c++ class member variable can be initialized only from inside the constructor.我正在寻找一种方法来确保只能从构造函数内部初始化 c++ 类成员变量。 It should not be set or overwritten by memory overflow.它不应被内存溢出设置或覆盖。 What can you suggest me for that?你能给我什么建议？

If you make the member const , it can be initialized in a constructor member initializer but it cannot be assigned.如果您使成员const ，则可以在构造函数成员初始化程序中对其进行初始化，但不能对其进行分配。 That may not protect it from memory overruns, however.但是，这可能无法保护它免受内存溢出的影响。 I'm not sure anything would.我不确定会有什么。
