Function overloading and return type In C++ and Java, functions can not be overloaded if they differ only in the return type. For example, the following program C++ and Java programs fail in compilation. (1)C++ Program 1#include<iostream>2intfoo()3{4return10;5}67charfoo() {//compiler ...

Working of overloading for the absolute() function In this program, we overload theabsolute()function. Based on the type of parameter passed during the function call, the corresponding function is called. Example 2: Overloading Using Different Number of Parameters #include<iostream>usingnamespace...

所谓函数重载(method overloading)即函数名称一样,但输入输出不一样。也就是说允许函数有各种不同的输入,根据不同的输入,返回的结果不同。jQuery之父John Resig提出了一个非常巧(bian)妙(tai)的方法,利用了闭包。 假设有如下一个需求,有一个people对象,里面存着一些人名,如下: ...
In Java, they are very rare because it's difficult to manipulate functions (although possible if you wrap them up in strategy-type objects). They are also rare in C++ because, while it's possible to create objects that work like functions ("functors") by overloading the `()` operator,...
