check unused variable in C project


I developed new C project and I use some time variables to debug or to check value ...

I want to be sure if I don't forget any unused variable after achieving project.

there is a Linux utilities or command to do that ?


Solution

  • Some compilers can issue a warning for you when an automatic variable is unused. Try

    gcc -Wunused-variable
    clang -Wunused-variable
