In the below example, we see how to swap two integers usingstd::swap()function. #include <bits/stdc++.h>usingnamespacestd;intmain() {inta=10, b=20; cout<<"Before swapping:\n"; cout<<"a: "<<a<<", b: "<<b<<endl;//swap nowswap(a, b); cout<<"After swapping:\n"; cout...

我怀疑它没有在C++98中是因为C++中唯一由编译器生成的函数是为了使类表现得像C结构体:您可以声明它们,销毁它们和复制它们。尽管默认的swap或默认的operator <可能非常有用(并且两者都可以通过按字段操作来实现),但C++标准希望拥有最少的默认函数,这样如果您不想要它,就有更少需要抑制的内容。C++0x中的function = ...

The std::swap() is a built-in function in C++ STL which swaps the value of any two variables passed to it as parameters. The std::vector::swap() function is used to swap the entire contents of one vector with another vector of same type and size. The std::swap() is comparitively...
对于STL容器,std::swap调用各自的成员函数swap(特化swap)。 C++11之前,模板对象是通过拷贝构造产生,并且经过了两次赋值(如开头的例子),T类型要求必须是可拷贝的;C++11之后,使用的是移动构造和移动赋值,如果类是可拷贝的(copy),但是没有声明移动操作(move),就会使用拷贝构造与赋值。如果类的移动操作(move)声明为del...
