Example code is shown below. I am just starting out and have seen examples in the declaration of the specific types instead however I don't know how to do this in the context of a struct.

contract Courses is Owned {

    struct Instructor {
        uint age;
        string fName;
        string sName;
    }

    mapping (address => Instructor) instructors;
    address[] public instructorAccts;

    function setInstructor(address _address, uint _age, string _fName, string _sName) onlyOwner public {

        var instructor = instructors[_address];

        instructor.age = _age;
        instructor.fName = _fName;
        instructor.sName = _sName;

        instructorAccts.push(_address) -1;
    }
}

Instructor storage instructor = instructors[_address];

hope it helps.

As the mapping declaration indicates, instructors maps to the Instructor type.

Instructor storage instructor = instructors[_address];
  • Thanks, yes I got confused by the syntax in the tutorial I'm following. – Ben Hook Jul 5 '18 at 20:14
