Project 1

This program calculates number of months needed for bunnies to reach a total of 100 and 1000 respectively

Declare n as integer “Number is the initial number ”

Input the number

Declare monthsCounter as integer

Set MonthsCounter to zero

Set total to n

WHILE newTotal is less than 100:

Set total to double the total

Increase monthsCounter by three

ENDWHILE

PRINT “The initial number of bunnies :”+n

PRINT “It takes monthsCounter months to reach to 100”

Set MonthsCounter to zero

Set newTotal to n

WHILE total is less than 1000:

Set total to double the total
Increase monthsCounter by three
ENDWHILE

PRINT “It takes monthsCounter months to reach to 1000”
