Could you edit your prior message and wrap your code in codeblocks (```)?

#

Could you also share the test output as text using a codeblock?

Do you want what have in Tests too?

#

Help with test ( in C ) I don't know what's wrong with it, first time using exercism

boreal hare
#

You shouldn't have a main() in your code. The unit test is the entry point.

#

Are you running the tests? How?

fringe karma
#

or a main in other local/code?

#

I'm learning programming now, because it I "guess" is correct, and because in vscode it works!

#

Just in exercism don't work, and now I'm here needing help

boreal hare
#

When you say it "works" in vscode, what does that mean?

#

Does it run the tests?

#

Do you understand how testing code works and how test driven development works?

Ty, I gonna read and give a feedback if my code works!

fringe karma

@boreal hare 🤦‍♂️ I'd just need to use

unsigned int square_of_sum(unsigned int number);
unsigned int difference_of_squares(unsigned int number);
and not
int number = 10, sum_of_squares = 0, square_of_sum = 0, difference_of_squares;

in my main
😩
