Copy from string

[Edward01]

Hi, I'm trying to copy from one string to another. But I have some problems with the code I guess.

void fun(char buffer[])
{
	int i = 0,k = 0;
	while(buffer[k] != ' ')
		k += 1;
	char* buff = new char[k];
	for(i = 0; i < k; i ++)
		buff[i] = buffer[i];
        cout<<strlen(buff);//14 instead of 4
	puts(buff);
}

int main()
{
	char buffer[12] = {"abcd dfd er"};
	fun(buffer);
	system("pause");
}

first of all if I try to do strlen(buff) I get 14 instead of 4, why is that?
and second when I do puts(buff) it prints me abcd and some random symbols.
how can I fix it?

system("pause"); I hate this, it`s a resource hog: http://www.cplusplus.com/articles/j3wTURfi/
