C++ STL std::swap() Functionswap() is a standard library function that swaps the value b/w any two objects. In C11, it has been moved under <utility> header. Below is the syntax details for swap().Syntaxvoid swap (T& a, T& b); Parameter...

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 = ...
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...

C/C++编程笔记:C++中的swap内置函数,用法详解 函数std ::swap()是C++标准模板库(STL)中的内置函数,该函数交换两个变量的值。句法:swap(a,b)参数:该函数接受两个必须交换的必需参数a和b。参数可以是任何数据类型。返回值:该函数不返回任何内容,它交换两个变量的值。下面的程序说明了swap()函数:示例一: #incl...
