Thread: String Class

Thank you, but "problems" are so generic. Learn to be a little more descriptive and not make others do so much of your work.

Try this:

Code:

const String & String::operator +=(const String & str)
{
	int newsize = getLength() + str.getLength() + 1; // Size of current + new string + '\0'.
	char *temp = NULL;
	if(newsize > size)
	{
		temp = new char[newsize];
		strcpy(temp, buf);
		delete []buf;
		buf = temp;
		size = newsize;  // Accidentally left this out.
	}
	strcat(buf, str.buf);
	stringlength = newsize;
	return *this;
}
