Question

Hi I’m teaching myself C++ and I’m getting this error

'verifyDateInput' was not declared in this scope

The error occurs on the call to verifyDateInput below.

    void setAll(std::string dateString) {

        if(verifyDateInput(dateString.c_str())) {

            std::vector<std::string> results = split(dateString, '/');
            month = results.at(0).;
            day = results.at(1);
            year = results.at(2);
        }
    }

I’m sure this is just some nuance of the language that I’m not getting. The function call is within a struct declaration in a header file, and within the header file I have the declaration of the function. (not sure if declaration is the right word…..the thing where I just write the function signature)

bool verifyDateInput(const char* input);

Thanks for any help!

So remember kids, always declare your functions above their usages in a program file. The problem was that my function declaration is below the struct declaration.

Thanks to Naveen and chris for immediately recognizing this
