Lambda表达式
摘要：
Lambda表达式其实就是个匿名函数，这种函数在程序中只使用一次，所以也就不用去特地定义和命名。Lambda的语法形式如下：[函数对象参数] (操作符重载函数参数) mutable或exception声明 ->返回值类型 {函数体}[函数对象参数]空。没有使用任何函数对象参数。=。按值传递了所有函数... 阅读全文

自对齐(self-aligned)
摘要：
C语言是自对齐的，32位以4字节对齐，64位以8字节对齐（1字节=8 bits)自对齐的好处：在一条指令内完成数据的取或者存的操作，使得内存访问更快；否则，如果一个变量跨机器字存储，那么要做两次或更多次的访问（先取存在前一个机器字的内容，再取存在后一个机器字的内容）。对齐要求：字符可以起始于任何字节... 阅读全文
