C Program To Find Strong Number

Learn How To Find Strong Number in C Programming Language. Check if a Number is a Strong Integer not in C Programming using Functions, While and For Loops. It is important that we should know How A For Loop Works before getting further with the C Program Code. Strong Number makes use of the Factorial Concept in C Programming.

    Is there any similarity between Strong Numbers and Armstrong Numbers in C Programming?

      Not at all. Apart from a small similarity in the name, there are no other similarities Sharmila.

    Is this Strong Number C Program frequently asked in the interview question? It seems a little tricky but easy to understand.

      I don’t think so. But, it’s an important concept that you must know. You never know if the interviewer asks you a program that has a similar concept! Try to understand the concept which is more important.
