You teacher is lifting the veil on unit testing. 👍

fervent perch Sep 7, 2022, 8:42 AM

#

so pretty much the code given i dont need to use it?

#

or do i need to use it to implement it inside of my code

lofty beacon Sep 7, 2022, 8:43 AM

#

Is the code you posted yours?
Or the teacher's?

fervent perch Sep 7, 2022, 8:43 AM

#

teachers

#

i had like premade code that the teacher made me download

#

and like add into vs

lofty beacon Sep 7, 2022, 8:45 AM

#

TRUE or FALSE?
You will have written _array_init() and _print_array().

fervent perch Sep 7, 2022, 8:47 AM

#

#

i have this in my thing

#

so there technically has the 2?

lofty beacon Sep 7, 2022, 8:52 AM

#

Okay, so you have those functions, but they are stubbed.

The teacher has given you some code. This code will test function _array_init(). And optionally it will also invoke _print_array().

You can just C&P that code into your file. I would suggest underneath functions _array_init() and _print_array().

In your main() you could call this test_init_array().
This is basically what a unit test would do under the hood.

#

ohhh ok

#

thanks for the help

lofty beacon Sep 7, 2022, 8:59 AM

#

Ah hang on.

#include "array_functions.h"

I didn't spot this until just now.

Are you working in a multi-file project?
If so, paste your teacher's code in the file that contains main().
It's probably called "main.cpp", but doesn't have to be.

fervent perch Sep 7, 2022, 9:00 AM

#

yea im working in multi file

#

#

i cnt find a file with main()

lofty beacon Sep 7, 2022, 9:01 AM

#

I see a file called "main.cpp".

fervent perch Sep 7, 2022, 9:02 AM

#

#

i added it in to this

#

is there a site where theres a explantion for the Includes

#

cuz some of the includes that were added in here i have never seen before

lofty beacon Sep 7, 2022, 9:04 AM

#

No, don't paste it inside of main().

Paste it above.
Then in main() add a call to this function.

#

Near the top of main.cpp you need to also add

#include "array_functions.h"

fervent perch Sep 7, 2022, 9:11 AM

#

i added the include inside of the main.cpp

#

#

i got this tho

fervent perch Sep 7, 2022, 9:13 AM

#

lofty beacon No, don't paste it _inside_ of main(). Paste it _above_. Then in `main()` add a...

wdym by posting it above like above int main(int argv, char **argv)

lofty beacon Sep 7, 2022, 9:14 AM

#

fervent perch i got this tho

It looks like you used <> instead?
Paste it just as I wrote it.

fervent perch Sep 7, 2022, 9:14 AM

#

oh

#

mb thanks for catching that

lofty beacon Sep 7, 2022, 9:17 AM

#

fervent perch wdym by posting it above like above ```int main(int argv, char **argv)```

Yes, copy the function above the function main().

bool test_init_array(bool debug=false)
{
   // the code
}

int main(int argv, char **argv)
{
   cout << "\n" << endl;
   // call function test_init_array() here
   cout << "\n\n=======================" << endl;
}

Something like this

fervent perch Sep 7, 2022, 9:18 AM

#

ohhh ok

#

and for the call functions

#

thats the thing where its like

#

private and public

lofty beacon Sep 7, 2022, 9:19 AM

#

No, that's for classes.
I cannot see any classes in your code.

fervent perch Sep 7, 2022, 9:19 AM

#

ohhh ok

#

is the " " supposed to be ' '

lofty beacon Sep 7, 2022, 9:21 AM

#

Maybe it should be

#include "includes/array_functions.h"

It's difficult to make out the directory structure from a project-view window - especially if it's not an IDE that I am familiar with.
That's my excuse anyway.

fervent perch Sep 7, 2022, 9:22 AM

#

LOL yea im like completely new to this

#

and like all this stuff i was introduced to never learned in my previous class

lofty beacon Sep 7, 2022, 9:23 AM

#

In fact, it might even be

#include "includes/array_functions/array_functions.h"

We could fix this in your CMakeLists.txt, but I fear that would take even longer and may just confuse.

fervent perch Sep 7, 2022, 9:24 AM

#

oh that one worked

#

for this include how come u used " " instead of < >

lofty beacon Sep 7, 2022, 9:25 AM

#

"" is for local files in your project.
<> is for system and library headers.

fervent perch Sep 7, 2022, 9:25 AM

#

ohhh ok

#

thanks for the help

#

if i have any more questions would i make a new post or just stick with this post

lofty beacon Sep 7, 2022, 9:26 AM

#

Up to you.
Might be easier for you to stick with this one.
Then you have all the information neatly in one thread.

fervent perch Sep 7, 2022, 9:27 AM

#

ok thanks for the help again

i had to include a array function in my code

#

i was given

#

#include "../../includes/stub/stub.h"

#

or add a array

#

but when i do

#

#include "includes/array_functions/stub/stub.h"

#

it doesnt work

#

#

#

i also tried to add it in front of the includes

#

and that didnt work as well

lofty beacon Sep 12, 2022, 7:52 AM

#

This is a matter of finding out where file stub.h lives relative to the source file from where you want to include it and the correct amount of ../ repeats.
Tedious and it's not something that any of us can give a definitive answer to.
I have techniques, but it requires the use of the command line.

fervent perch Sep 12, 2022, 7:53 AM

#

#

so essentially i would add it after the stub.h?

lofty beacon Sep 12, 2022, 7:55 AM

#

Okay, the header file "stub.h" doesn't appear to be "above" your project in the folder structure.
Try #include "includes/stub/stub.h"

fervent perch Sep 12, 2022, 9:01 AM

#

lofty beacon Sep 12, 2022, 9:35 AM

#

Does the file actually exist?
Again, not a champion on VStudio project views, but my suggestion appears to be correct based on your screenshot from before.

If you are proficient in command line use, perhaps cd to the project root directory and run

dir /s stub.h

fervent perch Sep 13, 2022, 1:28 AM

#

i have never used command lines before

exotic ibex Sep 13, 2022, 1:56 AM

#

show your CMakeLists.txt

#

that’s where you would configure include dirs

#

or at least for your actual build anyway

#

for just the syntax check your do that by installing and configuring the C++ extension for VSCode

exotic ibex show your `CMakeLists.txt`

i had to send as a file

fervent perch Sep 13, 2022, 3:54 AM

#

exotic ibex https://code.visualstudio.com/docs/languages/cpp

i also got this installed as well

fervent perch i had to send as a file

I’m on mobile rn, not going to download a file

fervent perch Sep 13, 2022, 3:56 AM

#

ok

#

uh for the wandbox

#

what do i do with it once i paste in the code

exotic ibex Sep 13, 2022, 3:57 AM

#

or use pastebin.com or gist.github.com or any of many similar sites

fervent perch Sep 13, 2022, 4:00 AM

#. . . . . . . . . . . . . . . . . .

#

like this?

#

this how u do it right

#

the thing is with this code my teacher was the one that provided that code

exotic ibex Sep 13, 2022, 4:02 AM

#

yes I see that

#

I’m not sure

#

in a case like this you really should have proper directions to follow given by your teacher

#

if not then go to office hours

#

or ask your TAs in the next lab

fervent perch Sep 13, 2022, 4:04 AM

alright thanks for the help tho
