This assignment will be in two parts, resulting in several source code files. Do part $1$ first, and then do part $2.$

Part $1-$ Building a calculator

The purpose of part $1$ is to build a "calculator" in C using functions. In particular, I want you to build a calculator with the following functions:

int getNumber$()-$ This function gets a number from the user and returns it$.$

int getOperator$()-$ This function get an operator $($character$)$ from the user and returns it$.$

int power$($int x$,$ int y$)-$ This function raises x to the power of y $($i$.$e$.,$ x$^$y$)$

int bottom$($int x$,$ int y$)-$ This function returns the floor of the x floor y $($floor returns the nearest integer value which is less than or equal to the floating point number of x $/$ y$)$

int rounded$($int x$,$ int y$)-$ This returns the closes integer to x $/$ y $($either larger or smaller$)$

Note: Your main$()$ should call getNumber$()$ twice to get the two numbers, then call getOperator$(),$ run the value returned by getOperator$()$ through a switch statement, and then call the appropriate function. You should print out the equation and the result. This should be in a loop so that you can enter numbers and call functions until the user chooses to exit.

Part $2-$ Build a module for your calculator.

Once you have completed Part $1,$ modify your code so that:

all of the functions are now in a $.$c file called

all of the function definitions are in a $.$h file called

Keep the main program from Part $1,$ but remove the functions.

Make sure your code runs when compiled with the appropriate $.$h file.

Deliverables:

Put Part $1$ and Part $2$ in two different folders, both of which are in a folder that is appropriately named as per the assignment submission instructions. Each part should have its own Makefile that does the appropriate compilation. Note that for Part $2,$ the $.$o file for the file should be generated on the first compile, but shouldn't be regenerated with subsequent compiles unless needed.

Upload as a $.$tgz file.

PLEASE NOTE: Several people have contacted me because their assignment uploads as $.$tgz files were "empty". You should be checking your $.$tgz files before you upload them to make sure that they worked.
