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...
unordered_multimap swap() function in C++ STL unordered_multimap::swap() 是 C++ STL 中的一个内置函数,用于交换两个 unordered_multimap 容器的内容。两个容器的大小可以不同。 语法: unordered_multimap_name1.swap(unordered_multimap_name2) 参数:该函数接受一个强制参数 unordered_multimap_name2,该参数指定...
multimap::swap() function is an inbuilt function in C++ STL, which is defined in header file. swap() is used to swap the content of the two multimap containers. This function swaps the values of two multimap containers irrespective of the size of both the multimap containers. When this f...

This function does not return anything.Example 1Let's look at the following example, where we are going to perform the swap between two optional objects.Open Compiler #include <iostream> #include <optional> int main() { std::optional < int > x1 = 11; std::optional < int > x2 = 22...
queue::swap()是C ++ STL中的内置函数,在头文件。queue::swap()用于交换队列容器的内容。此函数接受一个参数,这是我们希望与之交换关联队列容器的内容的另一个队列容器。 语法 myqueue1.swap(myqueue2); 此函数在第二个队列容器中接受一个参数,我们希望与之交换相关队列。
Scala的解释器在解析函数参数(function arguments)时有两种方式:先计算参数表达式的值(reduce the arguments),再应用到函数内部:或者是将未计算的参数表达式直接应用到函数内部.前者叫做传值调用(call-by-value),后者叫做传名调用(call-by-name). 传值函数和传名函数 object Add { def addByName(a: Int, b: =...
