这两个函数手动实现就很简单了,直接遍历一遍找最值即可,这里贴一下cppreference上的源码实现: 1//版本一2template<classForwardIt>3ForwardItmax_element(ForwardItfirst,ForwardItlast)4{5if(first==last){6returnlast;7}8ForwardItlargest=first;9++first;10for(;first!=last;++first){11if(*largest<*first...

http://www.cplusplus.com/reference/algorithm/min_element/?kw=min_element for the use of the third parameter. min_element/max_element expects a function[like] object that requires two parameters and a bool value as the return value.
Edit & run on cpp.shThanks. Feb 20, 2011 at 1:56am Athar (4466) Well, how is the compiler supposed to know what makes an employee "greater" than another? See here: http://www.cplusplus.com/reference/algorithm/max_element/ You'll need to implement operator< for your class or pass...
