Using cpplint to find typos in variable initialization

I want to check my code to find typos like this:

bool check;
check == true; // should be: check = true;

This is a valid code in C/C++, so I want to use cpplint to find code occurrences of this type.

What cpplint configuration should I use?

Solution

  • This typo indeed can be left unnoticed. I'd suggest you not to rely on default compiler configuration.

    Assume following code:

    int main()
{
        int check;
        check == 1;
}

    When built with gcc main.c -o main the compiler will not produce any warnings at all. (Ubuntu 20.04.1, GCC 9.3.0).

    However, when built with gcc main.c -o main -Wall:

    main.c: In function ‘main’:
main.c:4:8: warning: statement with no effect [-Wunused-value]
    4 |  check == 1;
      |  ~~~~~~^~~~

    You don't need cpplint for this kind of typos. That's an overkill.
