How to realize Polymorphism in C++

This article mainly introduces "how to achieve polymorphism in C++". In daily operation, I believe many people have doubts about how to achieve polymorphism in C++. The editor consulted all kinds of materials and sorted out simple and easy-to-use methods of operation. I hope it will be helpful for you to answer the doubts about "how to achieve polymorphism in C++"! Next, please follow the editor to study!

The polymorphism of C++ was realized.

# include

< iostream>

Using namespace std; class A {public: virtual void fun1 (int I) {cout

< < i< < endl; } public: virtual void fun2(int j) { cout< < j< < endl; } public: void fun(A &a) { a.fun1(1); fun2(5); } }; class B:public A { public: void fun1(int i) { i++; cout< < i< < endl; } public: void fun2(int j) { j++; cout< < j< < endl; } }; main() { A a; B b; b.fun(a); a.fun(b); return 0; } C++多态未实现 1 5 1 6 #include < iostream>

Using namespace std; class A {public: virtual void fun1 (int I) {cout < < I < < endl;} public: virtual void fun2 (int j) {cout < j < < endl;} public: void fun (A & a) {a.fun1 (1); fun2 (5);}}; class B:public A {public: void fun1 (int I) {ionization; cout < < I < endl;} public: void fun2 (int j) {jigsaw + Cout < j < < endl;}}; main () {An a; B b; b.fun (a); a.fun (b); return 0;} this ends the study of "how to achieve polymorphism in C++". I hope I can solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
