Question

In Coral programming: A half-life is the amount of time it takes for a substance or entity to fall to half its original value. Caffeine has a half-life of about 6 hours in humans. Given caffeine amount (in mg) as input, output the caffeine level after 6, 12, and 18 hours.
Ex: If the input is 100, the output is:

After 6 hours: 50.0 mg
After 12 hours: 25.0 mg
After 18 hours: 12.5 mg
Note: A cup of coffee has about 100 mg. A soda has about 40 mg. An "energy" drink (a misnomer) has between 100 mg and 200 mg.

Answer 1

Answer:

Yes, it will be after 6 hours: 50 mg, after 12 hours: 25 mg, and after 18 hours: 12.5 mg

Explanation:

Remember coral is a functional programming language and follows Pythons functional programming paradigm. Remember Python supports functional, imperative as well as OOPS paradigm.

The function will be:

def void calcamtleft(int amt):

   integer a=6

   integer time=6

   integer i=1

   while amt> 0:

       amt=amt/2

       print("After"+time+"  hours:" +amt+"mg")

       i++

       time=a* i

Hence in first loop amt=100

new amt=100/2=50

After 6 hours: 50 mg ( this will be printed)

i will increment then, and time will be = 6 *2 =12

now input amt=50

new amt=50/2=25

After 12 hours 25 mg (this will be output)

i will increment then, and time will be = 6 *3 =18

now input amt=25

new amt=25/2=12.5

After 18 hours 12.5 mg (this will be output)

i will increment then, and time will be = 6 *4 =24

now input amt=12.5/2= 6.25

new amt=6.25/2= 3.125

After 24 hours 3.125 mg (this will be output)

i will increment then, and time will be = 6 *5 =30

now input amt=3.125

new amt=3.125/2= 1.5625

After 30 hours 1.5625 mg

And this will continue till amt>0
