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++ Function Overloading Example (Different Parameters)

C++ Function Overloading Example (Different Parameters)

✅ C++ Program: Function Overloading with Different Parameters

#include <iostream>
using namespace std;

class Math {
public:
    void add(int a, int b) {
        cout << "Sum of two ints: " << a + b << "\n";
    }

    void add(double a, double b) {
        cout << "Sum of two doubles: " << a + b << "\n";
    }

    void add(int a, int b, int c) {
        cout << "Sum of three ints: " << a + b + c << "\n";
    }
};

int main() {
    Math m;
    m.add(10, 20);        // calls add(int, int)
    m.add(5.5, 2.5);      // calls add(double, double)
    m.add(1, 2, 3);       // calls add(int, int, int)
}

📘 Explanation:

This program shows Function Overloading in C++. The same function name add() is used with:

  • add(int, int) → Adds two integers
  • add(double, double) → Adds two doubles
  • add(int, int, int) → Adds three integers
The compiler chooses the correct function based on argument type and count.

🧾 Sample Output:

Sum of two ints: 30
Sum of two doubles: 8
Sum of three ints: 6

🔑 Keywords:

C++ function overloading, add function in C++, compile-time polymorphism, OOP concepts, C++ examples

📌 Hashtags:

#CPlusPlus #FunctionOverloading #CppExamples #Polymorphism #OOP #Programming

🔍 Search Description:

This C++ program demonstrates function overloading with different parameter lists (integers and doubles). Example of compile-time polymorphism with sample output.
