This C program finds and prints Armstrong number between two numbers. This example prints Armstrong numbers from 1 to a number entered by the user.
Armstrong number: A number is called an Armstrong number, if the sum of cubes of each digit is equal to the number itself. For example, 153 is an Armstrong number because 153 = 1*1*1 + 5*5*5 + 3*3*3 .
Program: C program to print Armstrong numbers from 1 to 1000.
Output: Armstrong numbers from 1 to 1000
Enter the upper limit, N: 1000 All Armstrong numbers from 1 to 1000: 0 1 153 370 371 407
The same algorithm can be used to check whether a number is Armstrong number or not.
