所以tmp会拷贝s1的数据 然后swap(tmp)就是让s2和tmp进行交换,因为this指针是s2 原因是string(const string& s)这个拷贝构造函数中的this指针就是s2,所以函数里面的this指针也默认是s2,交换后因为s2一开始就是指向的空,所以交换后tmp也指向空,而s2就指向tmp开出来的新空间 因为tmp是一个局部对象,出了作用域后就...
本次分析基于 CPython 解释器,python3.x 版本 在python2 时代,整型有int类型和long长整型,长整型不存在溢出问题,即可以存放任意大小的整数。在 python3 后,统一使用了长整型。这也是吸引科研人员的一部分了,适合大数据运算,不会溢出,也不会有其他语言那样还分短整型,整型,长整型… 因此 python 就降低其他行业的...
