Checking if a variable is initialized

Question

Seems like this would be a duplicate, but maybe it is just so obvious it hasn\'t been asked...

Is this the proper way of checking if a variable (not pointer) is init

Answer 1

If you donot like boost and c++17, the google c++ lib Abseil is another method to realize that. absl::optional is just like std::optional.

#include 
class MyClass
{
    void SomeMethod();

    absl::optional mCharacter;
    absl::optional mDecimal;
};

void MyClass::SomeMethod()
{
    if (mCharacter)
    {
        // do something with mCharacter.
    }

    if (!mDecimal)
    {
        // define mDecimal.
    }
}
