@sharad yeah. the code is giving warning as it should using the
flag.
2. Using which flag? How did you compile the code. Can you copy-paste
the warning?
what flags are you using? it might be the case that you haven't added
up the -W and - Werror flags ..
3. I used "-Wall" (after fixing the return type (and returning 0) and
using char *argv[]). The only warnings were about unused variables and
not about shadowing.
$ gcc -Wall test.c
test.c: In function ‘do_work’:
test.c:5: warning: unused variable ‘abc’
test.c: At top level:
test.c:1: warning: ‘abc’ defined but not used
