Thanks sorry for the edit...

So you mean that when i use buff in memset function for example, the compiler already looks at it as a pointer to the mem block, but when u uses the * it just points to the first section in the array?

In know, but cant find a damn thing on this particular subject.... im sorry.
Still bee nice if someone would answer me on what the consequences for a string without NULL is...

To me its looks...

What happens without the NULL.
Will it pickup data from memory until next NULL?

And when i do the:

str2[3] = "\0";

Get: warning: assignment makes integer from pointer without a cast

Dont i need to add the NULL?

Hello World!

If now i want to take the 3 first chars in a string, to compare them to something else.
How do i easiest only get those 3 chars of the string when i want to compare?

Thanks!

There is something i dont get :confused:

When i call the function:


nameOfFunction(str, sizeof(str));

Why isnt there & in front of str, cause it seems logical to me that you passes the...

What is a static variabel? and whats is void?

Simple question: How can i make a function return a string?

I have tried this:


char "name of function"(Arguments) {
char string1[16];
string1 = "Hello World";
return string1;
}

Thanks alot...

Hello World!

Hello World!

When i call inet_addr(string containing vaild ip address), i get back int back.

Hello World!


Structure.member

Okay here is the deal: i get that with this i statement i can reach the value "member" associated the single structure "structure". But when the statement looks...

Why is the result not 1?... :confused:

So i places the value of &my_addr in the struct sockaddr memory block.... right? and whats i the "*" good for? :confused:

I THINK i get it now, it makes &my_addr act like struct sockaddr * , but how can a memory address act like a structure ? :confused:

Thx alot! Elysia

So it takes the address of my_addr and place it in the structure sockaddr... Am i right?

Hello World!

(struct sockaddr *)&my_addr

What does this line do?... I am still trying to learn C :)
