In today video session we have to discuss a mathematical pr.problem, that is to find whether a number is Armstrong or not. Here we use while loop and switch statement for implementation of the algorithm. We start program by declaring all necessary variables which will be used throughout the program.
The entire program is divided into the following steps for checking Armstrong number.
1. If N is greater than 0
2. Take last digit (By taking remainder of N by 10)
3. Calculate cube of last digit
4. Sum cube into sum variable
5. Reduce number by last digit (By dividing number by 10)
6. Repeat from Step 1
After the completion of this while loop we will have digits cube sum into sum variable, so that we will compare the sum variable with the input variable. If these both are equal then it mean that provided number is Armstrong otherwise number will not an Armstrong number.
