In this article, we are going to execute a program “C Program to Find or Generate All Armstrong Numbers From 1 to n Range and Print on Console” successfully without facing any troubles. Yes, Let’s do it using this article.

## Source Code

``````/**
* C program to print Armstrong numbers from 1 to n
*/
#include <stdio.h>
#include <math.h>

int main()
{
int num, lastDigit, digits, sum, i, end;

/* Input upper limit from user */
printf("Enter upper limit: ");
scanf("%d", &end);

printf("Armstrong number between 1 to %d are: n", end);

for(i=1; i<=end; i++)
{
sum = 0;

/* Copy the value of num for processing */
num = i;

/* Find total digits in num */
digits = (int) log10(num) + 1;

/* Calculate sum of power of digits */
while(num > 0)
{
/* Extract last digit */
lastDigit = num % 10;

// Find sum of power of digits
// Use ceil() function to overcome any rounding errors by pow()
sum = sum + ceil(pow(lastDigit, digits));

/* Remove the last digit */
num = num / 10;
}

/* Check for Armstrong number */
if(i == sum)
{
printf("%d, ", i);
}

}

return 0;
