2 Ways To Check A Narcissistic Number in C Programming

Learn How To Find if a Number is a Narcissistic Number or not in C Programming Language. It is important that we should know How A For Loop Works before getting further with the C Program Code.

What is a Narcissistic Number?

If the Sum of Digits of a Number raised to the power of the number of digits is equal to the Number/Integer, then it is a Narcissistic Number. It is similar to an Armstrong Number.


Three Digit Narcissistic Integer:
153 = (1 * 1 * 1) + (5 * 5 * 5) + (3 * 3 * 3)

Four Digit Narcissistic Number:
8208 = (8 * 8 * 8 * 8) + (2 * 2 * 2 * 2) + (0 * 0 * 0 * 0) + (8 * 8 * 8 * 8)

This program takes every individual digit from the Integer and calculates the digit raised to the power of the number of digits in the Integer. Adding these powers of every digits and then comparing it with the Integer. If Sum is equal to the Integer, then it is a Narcissistic Number.

    Hey instead of taking digits from user, use on counter and get digits… it will help to generate armstrong/narcissistic number… Cheers…

      Yes Ashish! We can use even that approach to get the digits! Thanks for Information anyway! 🙂

  2. Avinash SAWANT

    How can we count the Number of Digits in the Input given by the User?

  3. Amey Shinde

    So, this is basically like an Armstrong Number with more than 3 digits, right?

  4. Aarav Rathod

    This seems to be similar to Armstrong Number. What I could sense is that when an Armstrong Number with 4 digits or more needs to be calculated then it is called as Narcissiatic Number, right?

  5. Ashish Bhatia

    So, finally I have found the 4 digit armstrong number c program. Thanks to the creator of this code.

  6. Srishti Thakur

    So, this 4 digit armstrong number program is valid for 5, 6, 7 digit armstrong number, right?
