Can someone explain to me the code below. I need to understand what line 2 and line 5 mean when we count digits of a number (ex. 100).
JavaScript
x
8
1
def Counting(Number):
2
Count = 0
3
while(Number > 0):
4
Number = Number // 10
5
Count = Count + 1
6
print("Number of Digits in a Given Number:", Count)
7
Counting(100)

Count

is the variable used to store the number of digits in Number.
JavaScript

while (Number > 0):
2
this line continues looping until the Number is 0. In other words it loops while Number is a positive integer.
JavaScript

Number = Number // 10
2
floor division of Number by 10. When you divide a number by 10, you are “removing” its last digit. For example, in the case of 100, it would be
JavaScript
1
2
1
100 // 10 = 10
2
or in the case of 12345,
JavaScript
1
2
1
12345 // 10 = 1234
2
this effectively reduces the number of digits by one.
JavaScript
1
2
1
Count = Count + 1
2
increments Count, as we have removed one digit from Number.
