C/C++编译错误收集-Wreorder成员未按顺序初始化

Posted 2022-12-16 奇妙之二进制

-Wreorder (C++ and Objective-C++ only)
Warn when the order of member initializers given in the code does not match the order in which they must be executed. For instance:

struct A
int i;
int j;
A(): j (0), i (1)
;
The compiler rearranges the member initializers for i and j to match the declaration order of the members, emitting a warning to that effect. This warning is enabled by -Wall.
