$2\mathrm{.}26$ LAB: Caffeine levels

A halflife is the amount of time it takes for a substance or entity to fall to half its original value. Caffeine has a half infe of about $6$ hours in humans. Given caffeine amount $($in mg$)$ as input, output the caffeine level after $6,12,$ and $24$ hours

Output each fioating point value with two digits after the decimal point, which can be achieved as follows

printf$("0\mathrm{.}21f^{**},$ yourvalue$)$;

Ex$.$ If the input is$.$

$100$

the output is

After $6$ hours: $50\mathrm{.}00mg$

After $12$ hours: $25\mathrm{.}00mg$

After $24$ hours: $6\mathrm{.}25mg$

Note: A cup of coffee has about $100mg.$ A soda has about $40mg.$ An "energy' drink $($a misnomes$)$ has between $100mg$ and $200mg$
