I have installed gdb and added -g option to my compilation command, but when I try (gdb) s or (gdb) n it says:

The program is not being run.

It only works when I try (gdb) r and goes and stops where my program stops because of it's error(that I could see this without gdb in command line).

How should I trace line-by-line my code?

    Add a breakpoint at some suitable location. – muru May 12 '18 at 6:12

You need to define a breakpoint, for example

break main

Then

run

and gdb will start your program and stop when it enters main.
