C Program to Check Prime Number Using Efficient Logic

  Introduction A prime number is a number that has exactly two distinct positive divisors: 1 and itself. In this program, we check whether a given number is prime or not using a simple and efficient logic. This type of program is commonly used in mathematics, competitive programming, and basic algorithm learning for beginners in C programming. Problem Statement The task is to write a C program that determines whether a given integer is a prime number or not. The program takes a single integer input from the user and analyzes its divisibility. If the number has no divisors other than 1 and itself, it should be identified as a prime number; otherwise, it is not prime. This problem is important in number theory and has practical relevance in areas such as cryptography, data validation, and algorithm design.  Algorithm / Logic Explanation To check whether a number is prime, we need to verify that it is not divisible by any number other than 1 and itself. The algorithm follows a si...

C++ Program to Demonstrate Single Inheritance

C++ Program for Single Inheritance (Parent and Child Class)

✅ C++ Program to Demonstrate Single Inheritance

#include <iostream>
using namespace std;

class parent {
  public:
    void parent1() {
        cout << "Hi I am parent class:\n";
    }
};

class child : public parent {
  public:
    void child1() {
        cout << "Hi I am child class:\n";
    }
};

int main() {
    child c;
    c.parent1();
    c.child1();
}

📘 Explanation:

This program demonstrates the concept of single inheritance in C++. - The parent class defines a function parent1(). - The child class inherits from the parent class using : public parent. - The child object can access both its own function (child1()) and the parent's function (parent1()).

🧾 Sample Output:

Hi I am parent class:
Hi I am child class:

🔑 Keywords:

C++ inheritance example, single inheritance in C++, parent and child class, OOP in C++, C++ object oriented programming

📌 Hashtags:

🔍 Search Description:

This C++ program demonstrates single inheritance where a child class inherits from a parent class. Includes example code, explanation, and sample output.
