Hello
for a c code i am using gcc compiler.
i have doubt using -c option.
for a c code the code compiles (without error ) with -c option even if i
don't provide prior declaration of function.
i mean i have try.c
//*******************
void my_func( ){
call_to_undeclared_func( );
}
//********************
i do : gcc -c try.c , it works.
is it the correct behaviour , i mean should it not ask for atleast
declearation of call_to_undeclared_func( );
like if my make the same as try.cpp then usen use the same command it
gives the foll. error.:
try.cpp: In function `void my_func()':
try.cpp:2: implicit declaration of function `int
call_to_undeclared_func(...)'
which i feel is expected behaviour.
Best Regards
Mamta
