Simple
Code: C
int add(int arr[10])
{
    int res = 0;
    for(int i=0;i<10;i++)
        res += arr[i];
    return res;
}

int main()
{   
    int arr[10] = {1,2,3,4,5,6,7,8,9,10};
    int x = add(arr);
    return 0;
}

Hi,

I need the coding without specifying the array size directly.that is u gave the array size as 10 na,for that we have to get the number from the user.

No problem juts use the pointer instead of aaray and use malloc to allocate the pointer and use like an array.

Please try to put it as a different thread as that will help even others to find the things easier.

I didn't really get your question, kindly explain!

Re: C coding
 
Scanf needs a pointer to the variable. Consequently, the "address-of" operator (&) is applied to the name of the variable. A C-string is not a single "thing", but a collection of such things (chars). The name of the array is treated as a pointer to its first element. Since it's already a pointer, the address-of operator is not required.

As Shabbir mentions, please put separate questions in separate threads. It's a matter of organization and promotes searchability.

Re: C coding
 
LOL! I took shakthi's '&' in the post for a literal AND and not the address-of operator!
