c++11 for_each結合lambda表達式的使用 高效優雅的代碼 有代碼有真相

#include <iostream>
#include <algorithm>#include <random>#include <time.h>int main(){    srand((unsigned int)(time(0)));    std::vector<int> a(10);    for_each(a.begin(),a.end(),[](int& x){x = rand()%10;});    for_each(a.begin(),a.end(),[](int& x){std::cout<<x<<" ";});    return 0;}
