Question

I have the following union:

union employee
{
    char key;

    struct manager
    {
        short int age;
        float shares;
        short int level;
    };

    struct worker
    {
        short int age;
        short int skill;
        short int department;
    };

} company[10];

How can I access a member of a structure which is inside the union employee?
I tried to access the age member of the manager structure this way:

company[i].manager.age

But I get error C2039: 'manager' : is not a member of 'employee'.

Answer 1

Add something after the tag declaration. Perhaps:

struct manager
{
    short int age;
    float shares;
    short int level;
} manager;

Side note: you’re not using the union right. The key, i.e. the field that tells you whether you are dealing with a manager or with a mere worker should be in an enclosing object, outside the union. Perhaps:

struct employee {
    char key;

    union {
        struct manager ...;
        struct worker ...;
    } u;
};

As dasblinkenlight notes, you could declare your manager / worker tags outside the union.
