Please do in clion c$99,$ the c and h file are at the end. I tried to post picutres but i only lets me do one now

Sheet Music Cost

This problem is based on problem $1$ of chapter $4.$ Your job is to build a function that does the calculation that

problem describes. You DON$$T have to do any input or output. The function you need to build is described

in this part of the $.$h file

$1//$ s i m p l e c o n d i t i o n a l

$2$ t y p e d e f enum c u s t o m e r $\_$ t y p e $\{$ t e a c h e r $,$ s t u d e n t $\}$ c u s t o m e r $\_$ t y p e ;

$3$ d o u b l e s h e e t $\_$ m u s i c $\_$ c o s t $($ d o u b l e p u r c h a s e $,$ c u s t o m e r $\_$ t y p e c u s t o m e r $)$ ;

You can see one function declaration there. The function$$s name is sheet$\_$music$\_$cost and it takes two

parameters: the purchase prices $($which is a double so it holds a real number$)$ and customer. For the variable

purchase, its type is double. For the variable customer, its type is "enum customer$\_$type". An enum is

essentially a list of possible values. You can see the declaration of customer$\_$type on the line $2$ of that code.

That$$s really two things put together:

$1.$ enum customer$\_$typeteacher, student defines two constants, teacher and student, that are a list of

possible values

$2.$ surrounding that with "typedef $...$ customer$\_$type" is declaring a new variable type for variables that

can only hold values in that enum. Now we can declare variables to have the type "customer$\_$type"

and those variables will only be able to have the value teacher or student.

For example, this will declare a variable and make it hold the value student

$1$ c u s t o m e r $\_$ t y p e s a l l y $=$ s t u d e n t ;

Back to our function declaration, the second parameter to sheet$\_$music$\_$cost is named customer and has the

type customer$\_$type. That means, we$$ll call the function like this:

$1$ s h e e t $\_$ m u s i c $\_$ c o s t $(122.00,$ t e a c h e r $)$

Hint: that the call for the first example in the book and, in that case, the function should return $112\mathrm{.}73.$

In your practice.c file, build the sheet$\_$music$\_$cost function.

Quadrants

The next problem is based on Chapter $4$ Problem #$6$: given an x and a y$,$ figure out which quadrant it is in$.$

Here$$s the framework from the $.$h file:

$1//$ c h a p t e r $4$ q u e s t i o n $6$

$2$ t y p e d e f enum q u a d r a n t $\{$ I $,$ I I $,$ I I I $,$ IV $\}$ q u a d r a n t ;

$3$ enum q u a d r a n t c h $4\_$ q u e s t i o n $6($ d o u b l e x $,$ d o u b l e y $)$ ;

Like the previous problem, this uses an enum for four quadrants. That$$s the return type of the function, so

you are supposed to return I, II$,$ III, or IV$.$ Some conditionals is all it should take.

c file code:

#include "practice.h$"$

#include

double sheet$\_$music$\_$cost$($double purchase, customer$\_$type customer$)\{$

$/*$ Your code here$*/$

return $0$;
