AI代码解释 // 点号+赋值符号Aa={.b=1,.c=2};// 冒号Aa={b:1,c:2}; Linux内核喜欢用.fieldname=value的方式进行初始化,使用指定初始化,一个明显的优点是成员初始化顺序和个数可变,并且扩展性好,比如在结构体非末尾处增加字段时,避免了传统顺序初始化带来的大量修改。 1.3 构造函数初始化 构造函数初始...
Positional Initialization is concise but requires careful ordering. Partial Initialization allows assigning a few members while setting the rest to default values. Using these methods provides flexibility and clarity, adhering to C standards for robust struct handling. ...
