c++ - 将类作为参数传递 c++

Question

与其这样做，不如继续为所有内容编写冗余代码:

Molecule::Molecule(Hydrogenyx& h){
    //some code
}

Molecule::Molecule(Carbonyx& c){
    //same code as hydro
}

Molecule::Molecule(Sulphuryx& s){
    //same code
}

有没有办法让它看起来像这样？:

Molecule::Molecule(x){
    //code that can apply to all
}

Answer 1

is there a way I can just make it so it can look like this?:

当然。您可以使用成员函数模板。

声明:

template <typename T> Molecule(T& t);

实现:

template <typename T>
Molecule::Molecule(T& t){
   // The common code.
}
