How to call a parent class function from derived class function in C++?
The following is an example to call parent class function from derived class function.
Example
#include <bits/stdc++.h>
using namespace std;
class p1 {
public:
void first() {
cout << "\nThe parent class p1 function is called.";
}
};
class d1 : public p1 {
public:
void first() {
cout << "The derived class d1 function is called.";
p1::first();
}
};
int main() {
d1 d;
d.first();
return 0;
}Output
The derived class d1 function is called. The parent class p1 function is called.
In the above program, a parent class p1 is created and a function first() is defined in it.
class p1 {
public:
void first() {
cout << "\nThe parent class p1 function is called.";
}
};A derived class is created, which is inheriting parent class p1 and overloading the parent class function first().
class d1 : public p1 {
public:
void first() {
cout << "The derived class d1 function is called.";
p1::first();
}
};The function of d1 class is calling the function of p1 class.
p1::first();
