由于函数和模板的重载具有相似性,所以他们的参数重载规则(overloading rule)也是相似的。1.4.2 泛型 lambda 表达式由于 C++ 不允许在函数内定义模板,有时候为了实现函数内的局部特殊功能,需要在函数外专门定义一个模板。一方面,这导致了代码结构松散,不易于维护;另一方面,使用模板时,需要传递特定的上下文(context)
#include <iostream> #include <conio.h> #include "CSpeed.h" using namespace std; //This is not overloading as the function differs only //in return type /*int Add(float x, float y) { return x + y; }*/ int main() { CSpeed speed; cout<<speed.AddSpeed(2.4f, 7.9f)<<endl; c...

it won't be perfect. There's obviously no operator overloading, and overriding (i.e. of "methods" in "derived classes") would have to be done by hand. Obviously, if you need "real" OOP, you'll want to use a language that supports it, such as C++. ...
