In this case if(0) will always be false but I want to execute line
(printf("I am here\n");) in gdb run. Could you please help me how to do
this

You can't. If your compiler is at all non-braindead, code inside a
conditional that is always false (e.g. 'if(0)') is omitted from the
final output.
You might be able to work around this by using 'if(foo)' where 'foo' is
a variable that is normally 0 but might possibly become non-zero. A very
safe way might be 'if(getenv("MY_FOO"))' (which will change execution
normally in the very rare condition that you set MY_FOO in the environment.
