changing default value for class::variable without object

Question

I receive an error that I cannot set delimiter without object. I am not sure where I went wrong.

main.cpp

using namespace sd;

int main() {
    Utilities::setDelimiter(',');
    return 0;
}

Utilities.h

namespace sd {
    class Utilities {

        static char m_delimiter;

        public:

        void setDelimiter(const char c) { m_delimiter = c;    }
        const char getDelimiter() const { return m_delimiter; }
    }
}

Utilities.cpp

namespace sd {

    char Utilities::m_delimiter = ',';

}

Does this answer your question? cannot call member function without object — Sander De Dycker

You must call a normal member function on a object instance:

Utilities util;
util.setDelimiter(',');

In your case, maybe changing it to a static method?

static void setDelimiter(....)

static void setDelimiter() removed my compile error... this is needed as one file use ',' and the other '|' as delimiter... both are stored inside an array of one object type vector<Item> inventory
