structure

hello guys,

can we use same name for both structure name and it's variable.

Yes, you can.

Code:

---

struct data
{
      int data;
}data;

struct
{
      int data;
}data;

---

Code:

---

struct Data_t
{
  int var;
};

---

struct Data_t Data;
...

That's how I would do it, rather than make the code confusing. Apparently the worst thing that you have to watch out for is defining a local variable within a function with the same name as a global variable (that might be in a #include file). That will get you into trouble. The use of '_t' stands for 'type'.

Code:

---

struct meaninglesslabel
{
  int var;
}Data_t;

---

I think this is better, it's been many years since I programmed.

Sure, they're in different namespaces so you can do something like this:

Code:

---

typedef struct foo
{
  int foo;
} foo;

---

From there you can only access the member foo by using the . or -> operators. Because of the typedef, you can also omit the required struct keyword when you create an instance of foo:

struct foo var;
or
foo var;

Will both create an instance of foo. This is because struct foo is the tag for a struct and thanks to typedef, foo is a new type, shorthand for struct foo { int foo; }. If you find that confusing, imagine this feature being used in real code. :P
