check for palindrome number prints the pattern of stars in decreasing order based on the input check whether the input number is a prime number print Fibonacci series of size n with first two numbers as 0, 1
Using Switch case and do-While loop provide all the above functionality, such that user can select the functions that he/she needs to perform and exit the program based on the input.
Function Explanations in Brief:
Palindrome number:
The numbers which give the same value when reversed are called palindrome numbers.
Example: 121, 12321, 512215, etc.,
Pattern of stars:
Based on the input integer, the levels in the pattern and the number of stars in each level are decided. At every level, the number of stars is 1 less than the previous level.
Example: If the input number is 4, then the output will be
****
***
**
*
if input no is 5, then the output will be
*****
****
***
**
*
If input no is 2, then the output will be
**
*
Prime number:
The numbers which are only divisible by 1 & themselves are called prime numbers.
(Or)
The numbers which have factors 1 and themselves are called prime numbers.
Example_1: If the input number is 23
Factors of 23 are 1, 23, and other than 1 it is divisible by 23 only
Hence the number is prime.
Example_2: If the input number is 22
Factors of 22 are 1,2, 11, 22 and are divisible by 2 and 11.
Hence the number is not a prime number.
Fibonacci series:
The series of numbers whose next number is the sum of its previous two numbers is called the Fibonacci series.
Example_1: If the input number is 5,
The Fibonacci series is: 0, 1, 1, 2, 3, 5 (by default first two numbers are 0 and 1)
Example_2: If the input number is 7 and the first two numbers are 3 and 4,
The Fibonacci series is: 0, 1, 1, 2, 3, 5 , 8, 13
Exit:
The program should ask the user to choose the task they want to perform after executing a task till the choice 0 is entered to exit the program.
