Armstrong Number in C Using Function

Armstrong Number in C Using Function. In this program, we can find whether the number is an Armstrong number or not using a function in the c program for beginners.

Armstrong Number Definition

The sum of the cubes of its own digits is equal to an Armstrong number, also known as a narcissistic number. 

As a result, narcissistic numbers are numbers that can be represented by manipulating their digits mathematically. 

A whole number, or integer, is the sum of its digits’ nth powers. 

Function Definition in C

A function is a collection of statements that work together to complete a task. 

Every C program contains at least one function, main(), and even the simplest programs can specify more functions. 

The name, return type, and parameters of a function are all specified in a function declaration. 

Armstrong Number in C Using Function

int func(int number)
int num = 0;
int power = 0;
int sum = 0;
int n = number;
num = n % 10;
power = num*num*num;
sum += power;
n /= 10;
if(sum == number) return 0;
else return 1;
int main()
int number;
printf("Enter The Number");
if(func(number) == 0)
printf("%d is Armstrong Number\n", number);
printf("%d is Not Armstrong Number", number);
return 0;


Enter The Number45
