Answer 1

The arguments of execl() is specifying the command-line arguments of the program to be executed.

execl("/bin/rm","rm /home/mazenas/Desktop/folder/","f.txt",NULL);

means to execute this:

"rm /home/mazenas/Desktop/folder/" "f.txt"

If you want to execute this command:

rm "/home/mazenas/Desktop/folder/f.txt"

You should write:

execl("/bin/rm", "rm", "/home/mazenas/Desktop/folder/f.txt", NULL);

Answer 2

I'm pretty sure you mean

 execl("/bin/rm","rm", "/home/mazenas/Desktop/folder/f.txt",NULL);

If rm checks its invocation name, then f.txt makes no sense and it complains; otherwise it's going to try to rm f.txt in the current directory rather than the given path.
