C compile error: Id returned 1 exit status

Question

For some reason, when I try compiling a program, the compiler says permission denied and Id returned 1 exit status. Could anyone tell me what that means? Thank you

   }
}

The above is the binary search algorithm code I tried to compile.

I may guess, the old instance of your program is still running. Windows does not allow to change the files which are currently "in use" and your linker cannot write the new .exe on the top of the running one. Try stopping/killing your program.
