HW7
COP-3223H

Setup

On eustis, you can create, compile, and run a homework in your assignments repo:

Log in to eustis
```
ssh NID@eustis.eecs.ucf.edu
```
Create a directory for your homework programs (if not already created):
```
mkdir -p ~/cop3223spring26/assignments/hw/
```
Enter the homework directory:
```
cd ~/cop3223spring26/assignments/hw
```
For each homework problem, use emacs to create and type out the homework problem, e.g., hw7-1.c:
```
emacs hw7-1.c
```
Compile and run the program to test it:
```
gcc -o hw7-1 hw7-1.c
./hw7-1
```
Repeat from step 4 as needed to get the correct program execution

Questions

(hw7-1.c) Hand-copy yourself without copy-and-paste the following program into a file on eustis and compile and run it.
```
#include <stdio.h>

int main(int argc, char **argv) {
  printf("%d\n", (22/7 +  355/113) / 2);
}
```
(hw7-2.c) Using only the C program template from class and without precomputing any intermediate values of the expression, write a program that computes \(10^2 - 7^2 - (10 - 7)(10 + 7) + 5\). There should be eight arithmetic operators in the expression (not counting parentheses). Create, cop

Submission

Submit the homework via git using whatever file names you used for the homework programs:

git add hw7-1.c
git add hw7-2.c
git commit hw7-1.c hw7-2.c
git push

Self-check

Remove the previous self-check

If you have already run the self-check, you can remove it like this

rm -rf ~/tmp/assignments_selfcheck

Double-check the path carefully to avoid deleting the wrong directory.

Make a fresh clone of your project

git clone gitolite3@eustis3.eecs.ucf.edu:cop3223/$USER/assignments ~/tmp/assignments_selfcheck

You should see something like

Cloning into '/home/net/NID/tmp/assignments_selfcheck'...

If you see

then remove the previous self-check.

Enter the fresh clone's hw directory

cd ~/tmp/assignments_selfcheck/hw

From here you can explore the repository to make sure that you have submitted the correct files for the given assignments. For instance, for this homework, make sure hw7-1.c and hw7-2.c are present and compile and run correctly.
