Check out example codes for "armstrong number in c". It will help you in understanding the concepts better.

Code Example 1

``````#include <stdio.h>
int main() {
int num, originalNum, remainder, result = 0;
printf("Enter a three-digit integer: ");
scanf("%d", &num);
originalNum = num;

while (originalNum != 0) {
// remainder contains the last digit
remainder = originalNum % 10;

result += remainder * remainder * remainder;

// removing last digit from the orignal number
originalNum /= 10;
}

if (result == num)
printf("%d is an Armstrong number.", num);
else
printf("%d is not an Armstrong number.", num);

return 0;
}``````

Code Example 2

``````#include <stdio.h>
#include <stdlib.h>
#include <math.h>

int cube(int a)
{
int c;
c =  a*a*a;
return c;
}

int armnum(int *a)
{
int x = *a, n = 0, rem, r = 0;
while (x != 0) {
x /= 10;
n++;
}
x = *a;
while (x != 0) {
rem = x % 10;
r += cube(rem);
x /= 10;
}
if(r == *a){
return 1;
}
}

int main()
{
int a, y;
scanf("%d", &a);
y = armnum(&a);
if(y == 1){
printf("It is an Armstrong number.");
}
else{
printf("It is not an Armstrong number.");
}
}``````
