Please write this in C$++$ using a while and if loop. Radioactive Decay

This problem is based on the explanation of Chapter $5$ Problem #$14.$ That problem describes how you

calculate radioactive decay from a half life. This is the function you must build:

$//$ Chapter $5$ question $/4$

int years$\_$to$\_$decay$($double starting$\_$amount, double target$)$;

Given a start$\_$amount of Cobalt$-60$ and a target for how radioactive you want it to be$,$ you must compute

how many whole years it will take to get below that target. The return type of this is an int, so you can just

walk through years from $1$ to whatever until the amount remaining is less than the target.

With C$,$ there's a little complication to this. You need the constant for $e.$ If you include math.h$,$ you'll get

a constant M$\_$E that evaluates to $e.$ That include file also gives you pow $(x,y)$ that raises $x$ to the $y^{th}$ power.

However, there's where the complication comes. In order to make the compiled files as small as possible,

the linker only includes the bare minimum functionality. I think that requires a bit more explanation $...$

So$,$ with this project, our code is in two separate $.$c files. The compiler actually compiles each of them

separately. Then another program, called the linker, puts those compiled files together to build the runnable

file. The linker also includes code for things like printf. However, in order to keep our executables small,

the linker only includes the bare minimum of extra libraries. We're going to have to figure out how to tell

it to include the math library. $($Yes$,$ it feels like we did that when we included math.h$.$ That was enough to

make it compile, but the $.$h file only includes descriptions of the code. Now we have to tell the linker where

to find the functions that math.h referred to$.)$ There's one more file in your project that is telling the machine

how to put the stuff together to build your executable. CMakeLists.txt:

cmake$\_$minimum$\_$required$($VERSION $3\mathrm{.}16)$
