Loop Statements:
================
-> also called as "Iterative Statements".
when we can use?
================
when we want execute the block of code more than one time continuously, then we can use "loop statements".

Ex: Hi for 5 times

1. print("Hi")
2. print("Hi")
3. print("Hi")
4. print("Hi")
5. print("Hi")

-> we have two types of loop statements:
	1) while loop
	2) for loop
-> loop statements can work on three things:
	1) Initialization ==> describe the start of the loop
	2) Condition ==> until which the loop can execute
	3) Update ==> can be increment/decrement to traverse from start to end step by step

1) while loop:
==============
Syntax:
	initialization for while loop
	while condition:
		statements (while loop body)
		update
	next statement

Note:
====
If update statement is absent in while loop body, the loop can be infinite.

# WAP TO PRINT HELLO FOR 10 TIMES USING WHILE LOOP

line = 1    # initialization
while line <= 10:   # condition
    print("Hello")
    line = line + 1 # update
print("Loop Operation was stopped because line has reached a value of 11.")
print(line)

======================================================
# WAP TO PRINT THE NUMBER OF DIGITS OF A GIVEN NUMBER.

number = int(input("Enter a number:"))  # 987654
countDigits = 0

n = number  # initilization
while n > 0: # condition
    indDigits = n % 10
    countDigits = countDigits + 1
    n = n // 10 # update

print("The number of digits of",number,"is = ",countDigits)
=====================================================

# WAP TO PRINT THE REVERSE OF THE GIVEN NUMBER.

number = int(input("Enter a number:"))

n = number  # initialization
reverseNumber = 0

while n > 0:    # condition
    digits = n % 10
    reverseNumber = reverseNumber * 10 + digits
    n = n // 10 # update

print("The Reverse of",number,"is = ",reverseNumber)

Assignment:
===========
WAP TO FIND THE SUM OF DIGITS OF A GIVEN NUMBER.

98765 ==> 9 + 8 + 7 + 6 + 5 ==> 35
