passing array to function

Hi,
If I want to pass an array to a user-defined function, do I pass the array with it's index inside it,

Code:

---

int Func(int score[num_of_scores])

---

or do I have to pass the index separately?

Code:

---

int Func (int score[], int num_of_scores)

---

>or do I have to pass the index separately?
Short answer: Yes.

So thats all?

Why don't you try it and find out?

ok. I don't know if im doing this right. It compiles but comes out all wrong.

Code:

---

#include <stdio.h>
#define SIZE 5
void Func(int,int,int);

main()

{

        int array[SIZE] = {1,2,3,4,5},
                index=0,
                a=0;

                Func(index,array[SIZE],a);
               
}

void Func(int index,int array[SIZE],int a)

{

        for(index=0; index<5; ++index)
        {
                a = array[index];
                printf("\n%d" , a);
        }       
                       
                       

       
}

You dont need to use square brackets, or specify the size of the array when you pass an array, therefore:

Func(index,array[SIZE],a);

becomes

Func(index,array,a);

that is correct (you got it first Welschy :D)

also, you dont have to assign the number of elements of a unidimensional array when passing it to a function:

Code:

---

void Func(int index,int array[SIZE],int a)

---

could be

Code:

---

void Func(int index,int array[],int a)

Thanks,
It does need to be in the definition header right?
edit> At least the brackets?

Yes, it needs the brackets in the definition and prototype.

I do get these warnings:

int ' differs in levels of indirection from 'int [5]' (line 13)
'Func' : different types for formal and actual parameter 2 (line 13)
formal parameter 2 different from declaration (line 19)

did you mean definition and declaration?

As I said, you need the brackets in the prototype.

Code:

---

void Func(int,int [],int);

Ok. I've never seen that done before :eek:

Thanks that kills the warnings.
