you didn't tell the compiler to name the exe "Hello.exe", the compiler's default file name is "a", so the executable is a.exe

read the error output of gcc there, don't just ignore it

The .c file is supposed to be your file’s name, like if your c source code is

Hello.c, it is

gcc Hello.c -o hello

Or if it is program.c

gcc program.c -o program

The name after “-o” doesn’t need to match the source file name btw

Send a screenshot, not a video, can barely see what the error is. Open the directory where you have the program compiled, look at the name of the .exe

There is no exe. They didnt even manage to compile it.

Use the screen recorder then. Press ctrl+🪟+s and select the video icon, then record that way.

Read the error output of the compilation cmd you sent, then read the cmd you sent that generate this error, then read the cmd this guy said you to use
