        • redundant

        Why is this an issue?

        Redundant declaration specifiers should be removed or corrected. Typically, they represent bugs. A specifier modifies the type or pointer to its left. Only when it is at the far left does it apply to the right.

        Noncompliant code example

        const int const * v1a; // Noncompliant; both const specifiers apply to int
        const int const * v1b; // Noncompliant
        static static int v2;  // Noncompliant
        

        Compliant solution

        const int *       v1a;  // pointer to a const int. same meaning as before but less confusing
        int const * const v1b;  // const pointer to a const int
        static int         v2;
