Finding whether a number is an Armstrong number

An Armstrong number is a three-digit integer that is the sum of the cubes of its digits. This simply means that if xyz = x³+y³+z³, it is an Armstrong number. For example, 153 is an Armstrong number because 1³+5³+3³ = 153.

Similarly, a number that comprises four digits is an Armstrong number if the sum of its digits raised to the power of four results in that number. For example, pqrs = p⁴+q ⁴+r ⁴+s⁴.

How to do it…

1. Enter a number to assign to the n variable:

printf("Enter a number ");
scanf("%d",&n);

2. Invoke the findarmstrong function. The value assigned to n will get passed to this function:

findarmstrong(n)

3. In the...
