Hi!
I have a two string arrays, that I sent over the network, but the problem is that when I define them, GCC adds null at the end. I know it sopose to be like that, because it's string termination character, but I need to be able to define array, without it! Any suggestions? Thank you!
At the other end, just eliminate the null character.
Send only bytes of strlen().
my_arr[last_element] = null; ?Originally Posted by manutd
I'll try that out right now!
If it doesn't have a null character, it's not a string. A string by definition is zero or more characters terminated by a null character. Thus, if you omit the null character, you no longer have a string, you just have an array of characters.As such, you should not be using string based functions on it.Code:char notastring[10] = { 'n', 'o', 't', 'a', 's', 't', 'r', 'i', 'n', 'g' };
Quzah.
Hope is the first step on the road to disappointment.
Whatever you do with strings, the nice thing is they are still just arrays terminated with a null character, strlen allows you to know the size of the string and position of the null character, so you can handle it as either a string or an array of chars, in whatever way is convenient.

So what's so hard about
char buff[ ] = "hello";
Yes there is a \0 at the end, but it's dead easy to ignore it by doing
send( buff, strlen(buff) );
rather than
send( buff, sizeof(buff) );
If you're receiving a \0, then the only reason is that you sent a \0.
It's simply a matter of being able to count, and using the return result of various functions.
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
