Longest Substring Without Repeating Characters Given a string s , find the length of the longest substring that contains no repeating characters. A substring is a continuous part of the string, so "pwke" is a subsequence of "pwwkew" but not a substring. Approach We use a sliding window . The window is the part of the string between start and end , and we always keep it free of repeated characters. An array lastIndex of size 128 remembers the most recent position of every ASCII ...

C++ Program for Multiple Inheritance (Grandparent, Parent, Child)

C++ Program for Multiple Inheritance (Grandparent, Parent, Child)

✅ C++ Program to Demonstrate Multiple Inheritance

#include <iostream>
using namespace std;

class grandparent {
  public:
    void gp() {
        cout << "Hi I am your grandparent:\n";
    }
};

class parent {
  public:
    void p() {
        cout << "Hi I am your parent:\n";
    }
};

class child : public grandparent, public parent {
  public:
    void c() {
        cout << "Hello I am your child:\n";
    }
};

int main() {
    child obj;
    obj.gp();
    obj.p();
    obj.c();
}

📘 Explanation:

This program demonstrates the concept of multiple inheritance in C++. - The grandparent class has a function gp(). - The parent class has a function p(). - The child class inherits from both grandparent and parent. - The child object can call functions from both its parent and grandparent, along with its own function.

🧾 Sample Output:

Hi I am your grandparent:
Hi I am your parent:
Hello I am your child:
