Does MAC address necessary for packet delivery?

I am newbie in Networking. I have just started studying Networking.
I have a doubt

It is not explicitly mentioned whether we can use pointers or not. I was also thinking to use pointers. Is there any other method possible?

Reversing string without using indexing..
Hello all,
I encountered a programming problem while going through interview questions asked by companies. But I stuck at this:
Given an array of characters. How would you reverse it? How would you reverse it without using indexing in the array?
Please Help..

But I wanted to ask why this method is better because subtraction bears overhead like multiplication.

Fastest way to mulitply by 7
Hello all,
I got the answer that fastest way to multiply by 7 is n<<3 - n, but why?
If the question is to multiply by 8, then n<<3 is considerably better than n*8, because bitwise operation is faster. But when we multiply by 7, we are also subtracting n, it may be more cumbersome than multiplying directly with 7.
please answer,

int a[1];
};
int main()
{
struct exp s;
for(int i=0;i<4;i++)
s.a[i]=i;
cout<<endl;...Leave a comment:
