🙋 Introduction

In the domain of programming, solving problems related to numerical comparisons is a common task. One such problem is determining the largest among three given numbers. This is a fundamental operation in many algorithms and applications.

In this tutorial, we will walk through a C++ program designed to find the biggest among three numbers. The program compares the values and identifies the maximum, showcasing a fundamental concept in programming logic.

📄 Example

Let's delve into the C++ code that accomplishes this task.

FindBiggest.cpp

Copied

#include <iostream>

class FindBiggest {
  public:
    // Function to find the biggest of three numbers
    static int findBiggest(int num1, int num2, int num3) {
      if (num1 >= num2 && num1 >= num3) {
        return num1;
      } else if (num2 >= num1 && num2 >= num3) {
        return num2;
      } else {
        return num3;
      }
    }
};

// Driver program
int main() {
  // Replace these values with your desired numbers
  int number1 = 14;
  int number2 = 7;
  int number3 = 22;

  // Call the function to find the biggest number
  int result = FindBiggest::findBiggest(number1, number2, number3);

  // Display the result
  std::cout << "The biggest number is: " << result << std::endl;

  return 0;
}

💻 Testing the Program

To test the program with different numbers, simply replace the values of number1, number2 and number3 in the main function.

Output

The biggest number is: 22

🧠 How the Program Works

The program defines a class FindBiggest containing a static method findBiggest that takes three numbers as input and returns the largest among them using conditional statements.
Inside the main function, replace the values of number1, number2, and number3 with the desired numbers.
The program calls the findBiggest method, and the result is displayed.

🧐 Understanding the Concept to find the Biggest of three Numbers

Before delving into the code, let's understand the concept behind finding the biggest of three numbers. The program uses conditional statements (if-else) to compare the values and determine which is the largest.

For example, consider the numbers 14, 7, and 22. The program evaluates and identifies 22 as the largest number.

🎢 Optimizing the Program

While the provided program is straightforward, consider exploring and implementing alternative approaches or optimizations for determining the maximum of three numbers.

Feel free to incorporate and modify this code as needed for your specific use case. Happy coding!
