In C++, access specifiers are used to control the accessibility of a class member. The three main access specifiers are:n
1. Private (private): Members declared as private can only be accessed within their own class.nExample: `class Example {n private:n int x;n};`n
2. Protected (protected): Members declared as protected can be accessed by the members of their own class, derived classes, and friends of the class.nExample: `class Base {n protected:n int y;n};nclass Derived : public Base {n void print() {n cout << y;n }n};`n
3. Public (public): Members declared as public can be accessed by any function that has the object of the class.nExample: `class Example {n public:n int z;n};nvoid main() {n Example obj;n cout << obj.z;n}`nnThe key differences are in the accessibility level, with private having the lowest and public having the highest level of accessibility.
