typedef for arrays?

Hi,

I would like to introduce a new type for something like that

Code:

---

char name[32];

---

to avoid inconsistence over the project (in case the same array size is needed somethere else)

Code:

---

typedef NAME_T char[32] // doesn't work
NAME_T name;

---

Is this possible somehow for arrays?

Thank you!

Make a header file?

Why do you want to, especially for native arrays when you can use std::vector?

How about

Code:

---

typedef char NAME_T[32];

---

It is. But how would that help me avoiding to rely on that nobody changes that 32 to 64 for example (my module would break in that case if it has the 32 hardcoded inside)?

Hm, it's

Code:

---

class ...
{
  NAME_T name;

  ctor()
  {
    //copy to name
  }

};

versus

class ...
{
 std::vector<char> name;

  ctor()
  {
    name.resize(name_len);
    if(0 < name_len)
    {
        //copy to &name[0];
    }
  }
};

---

more writing for what advance? ok, maybe the getter for name could return by value instead of const char*...

That works!

Thank you all so far!

or std::string.

Native arrays are perfectly fine for some tasks.

I wouldn't define a typedef for arrays, though. I'd define a constant for the size and simply use that everywhere.
