c++11 for_each结合lambda表达式的使用 高效优雅的代码 有代码有真相

#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;

}
