πŸ™‹ Introduction

In the realm of programming, various tasks involve manipulating and transforming numbers. One interesting problem is condensing a number, which means reducing a number by summing its digits until a single-digit number is obtained. This process is often referred to as finding the digital root or digit sum.

In this tutorial, we will explore a C program designed to condense a given number. The program involves repeatedly summing the digits of the number until a single-digit result is achieved.

πŸ“„ Example

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

condenseNumber.c
Copied
Copy To Clipboard
#include <stdio.h>

// Function to condense a number
int condenseNumber(int number) {
  // Continue summing digits until a single-digit number is obtained
  while (number > 9) {
    int sum = 0;

    // Sum the digits of the number
    while (number > 0) {
      sum += number % 10;
      number /= 10;
    }

    // Update the number with the sum
    number = sum;
  }

  // Return the condensed number
  return number;
}

// Driver program
int main() {
  // Replace this value with the number you want to condense
  int number = 9875;

  // Call the function to condense the number
  int condensedNumber = condenseNumber(number);

  // Display the result
  printf("The condensed form of %d is: %d\n", number, condensedNumber);

  return 0;
}

πŸ’» Testing the Program

To test the program with different numbers, modify the value of number in the main program.

Output
The condensed form of 9875 is: 2

🧠 How the Program Works

  1. The program defines a function condenseNumber that takes an integer number as input and condenses it by summing its digits until a single-digit result is obtained.
  2. Inside the main program, replace the value of number with the desired number you want to condense.
  3. The program calls the condenseNumber function and prints the result.

🧐 Understanding the Concept of Condensing a Number

Before delving into the code, let's understand the concept behind condensing a number. The process involves repeatedly summing the digits of the number until a single-digit result is achieved.

For example, consider the number 9875. The program would calculate 9 + 8 + 7 + 5 = 29, then 2 + 9 = 11, and finally 1 + 1 = 2. The condensed form is 2.

🎒 Optimizing the Program

While the provided program is straightforward, consider exploring and implementing alternative approaches or optimizations for condensing numbers.

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