Zum Schluss werden beide Variablen noch einmal XOR-ed und das Ergebnis wird in der zuerst modifizierten Variable - in diesem Fall y - gespeichert. Diese Implementierung beinhaltet mehr Maschinencode-Anweisungen, wenn sie ohne Optimierungsflags kompiliert wird, und führt daher zu einer re...
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...

Description 编写用来交换两个数的函数,使得“Append Code”中的main()函数能正确运行。 用C实现三个函数int_swap()、dbl_swap()、SWAP(),其中SWAP()是个带参宏。 用C++实现两个函数,都以swap()命名。 以上函数的调用格式见“Append
A swapping values:In C and in Java, we can always swap values with the use of three assignment statement and no function or paramters. The code on the left shows this, while the code on the right shows how the same task can be accomplished using the Cexclusive-oroperator^. (Notice th...
