tuple与pair有些类似,但是tuple支持多个元素,多种元素类型,在希望将一些数据组合成单一对象,但不想麻烦地自定义数据结构表示时很有用,tuple是一个“快速而随意”的数据结构 定义和初始化tuple 定义格式为tuple<T1,T2,T3...>name;,使用构造函数初始化,或者在tuple内元素类型相同时使用参数列表进...

Implementations that do not support TR 29124 but support TR 19768, provide this function in the headertr1/cmathand namespacestd::tr1. An implementation of this function is alsoavailable in boost.math. beta(x, y)equalsbeta(y, x).
The computer company you work for is introducing a brand new computer line and is developing a new Unix-like operating system to be introduced along with the new computer. Your assignment is to write the formatter for the ls function.
