Hi, so this may be a VERY noob question but when i try and compile a program using gcc it always says "there is no such file or directery" or "gcc: no input". I am just trying to get the a.out i think but not sure. I am using the command "gcc firstprog.c", am I doing something worng? Thanks for your help and please go easy on me I am new to this haha

What program are you trying to compile?

If your current working directory is the same as where the source file is stored, it's usually something like:

gcc filename.c
where "filename.c" is your source file.

You can also use:

gcc filename.c -o outputfile
(where "outputfile" is the name you want to give the executable program)

If you use the first one and there are no errors, you can run the program with:

./a.out

With the second example, you can run the program with:

./outputfile



Use the "cd" command to navigate to the directory where the source file is stored.

you should probably get familiar with a few basic commands.
