lambda表达式学习1

#include <array>#include <algorithm>#include <iostream>using namespace std;template<typename T,size_t N>ostream& operator << (ostream& os,array<T,N> const& a) {for(auto m:a){ os<<m<<' ';}return os;}int main(){const int SIZE=10;array<int,SIZE> a;generate_n(a.begin(),SIZE,[](){return rand()%100;});for_each(a.begin(),a.end(),[](int m){cout<<m<<' ';});cout<<'\n'<<a<<endl;return 0;}

嗯，就酱~~~
