枚举或带有类型的typedef

Question

I'd like to create a simple object that I can access like this:

myobject.floatValue1 = 1.0;
myobject.floatValue2 = 2.0;

It shouldn't have anymore than the two properties. Is it possible to create an enum or typedef with such a simple structure. Or must I create a class?

Answer 1

Sure, just make a C structure:

struct myStruct 
{
    float floatValue1;
    float floatValue2;
};
typedef struct myStruct myType;

Then use it like this:

myType myVariable = {0.0, 0.0}; // optional initialization
myVariable.floatValue1 = 1.0;
myVariable.floatValue2 = 2.0;

Answer 2

Take a look at using a struct , eg:

struct MyObjectType {
    float floatValue1;
    float floatValue2;
};

...

MyObjectType myobject;
myobject.floatValue1 = 1.0;
myobject.floatValue2 = 2.0;
