在初始化中加倍'='

Question

当我做一些实验时,我遇到了这条线:

 int home_address = current_pos_ = hash(key, size_);

而我想知道它究竟是做什么的？(不是哈希函数或任何东西,只是"int variable = variable = value;"的东西)

Answer 1

该表达式如下:

int home_address = (current_pos_ = hash(key,size_));

其分配的结果hash(key,size_)为current_pos_它然后分配的值current_pos_成home_address.
