Protected Permission

“protected” is one of the “Member Access Specifier”,.

protected class member can be accessed by the object in the current class and derived class, but not in another class.

Example 5.10

#include <iostream>

using namespace std;

class A {

protected: // define protected permission

int prot; // declare a protected member

};

class B: A { // inheritance

public:

void myfunction(){

prot = 100 ; // access protected member, ok !

cout << prot;

}

};

int main(){

B obj;

obj. myfunction();

return 0;

}
