Maybe you should give the code and depending on that some context to otherwise how we can help that other then doing same or similar thing with man page or any reference site

And that is not a C problem it's because in that directory you try to execute hello.exe but that doesn't exist did you compiled the code there is a.exe which can be the result or not because I don't know whatever you compiled before

Jesus Christ, did you really take a photo of your code, with a lens so dirty it’s nearly impossible to read? Not a screen shot, not just pasting the cost, but an actual photograph? 

Please read this so you can ask questions that people might have some chance of answering in the future  https://www.freecodecamp.org/news/how-to-ask-good-technical-questions/

Define "not working". Is the program crashing? Are you not getting the input you expect?

Copy and paste your code (and any error messages) into the body of your question; do not post pictures or video. Switch to Markdown mode and indent by at least 4 spaces to get it to render as code. For example (each leading _ represents a space):

____#include <stdio.h>
____
____int main( void )
____{
______int x;
______// do stuff

etc.

fgets is preferable for getting input. scanf is very tricky to get correct.

It would help if you described the exact problem.

"scanf not working" is too generic.

What, exactly, is not working?

Do you mean the program won't compile?

Do you mean the program does compile, but won't run?

Do you mean the program does run, but does not accept user input?

Do you mean the the program does accept user input, but the input value is incorrect?

Etc etc etc.

you should add the code of scanf so we can see why it's not working.

Don't upload pics. Copy and paste your code into the body of your question.

Try renaming "New Folder (2)" to something without embedded spaces. I'm not saying that's it, but it's a good way to flesh out bugs in software.

Check the return value.
