Redefination problem

Hi,
I have a main.c file like this

Code:

---

#include "Headers.h"
extern char *myArray;
int main()
{
    return 0;
}

---

the Headers.h file contains
char myArray[200];

When I compile this is giving error like redefination; different types of indirection

But my doubt is we can use pointers instead of arrays

please clarify me whether we can use extern with pointer or not

You probably should declare myArray as extern in the header:

Code:

---

extern char myArray[];

---

Then in main.c you define it:

Code:

---

char myArray[200];

---

Thanks for the quick response.
I changed the way you told.
It is working fine.

But my question is -- I can use pointer also in the main.c file

like char *myArray

But it is giving the compilation error -- like redefination; different types of indirection

I do not know what is your question, but a pointer is not an array, and an array is not a pointer.

To get a pointer to your array you could do something like :-

Code:

---

char* ptr = &myarray[0];

---

Be extremely careful using that pointer though, as by accessiing your array this way, the compiler has no idea of its bounds.

It is not possible to declare variables of the same name twice.
You have already declared array 'myArray', if you want to declare a pointer to it, name it differently, e.g.

Code:

---

char *myArray_ptr = myArray;

---

Next time show the exact error message, line of code where the error is.
