I'm creating a default constructor for a struct and setting all values to 0, but there is a substruct and value (Date birthDate) referenced and I'm not sure how to handle it.

The Date struct includes 3 integers: day, month, year. Combined they = birthDate.

Reptile::Reptile(){
    species = " ";
    DangerAssessment dangerAssess = "";
    Date birthDate() = 0;
    SizeOfEnclosure sizeofenclosure;
    exhibitName = " ";
    }

  • cant you assign it with something like Date birthdate = Date(0,0,0) ? Commented Feb 17, 2018 at 1:39
  • Use the Member initializer list.. Should look something like Reptile::Reptile(): species(""), dangerAssess(""), birthDate(0), sizeofenclosure(0), exhibitName("") { } If you are calling default constructors you can leave them out. They will be default constructed. minimal reproducible example required for more specific information. Commented Feb 17, 2018 at 1:41
  • @AntiMatterDynamite I'm afraid not. That would make and initialize an Automatic variable scoped to only exist within the body of the constructor. It would not initialize or assign a member variable. Commented Feb 17, 2018 at 1:47

  • @Hannah but its ok to have it be Date birthDate() = 0 what do you want to be there? Commented Feb 17, 2018 at 2:09
