    It's me again.........I need help once more. (Very short)

    Code:
    void String::operator+=(const String& rhs)
    {
    	unsigned short rhsLen = rhs.GetLen();
    	unsigned short totalLen = itsLen + rhsLen;
    	String  temp(totalLen);
    	unsigned short i;
    	for (i = 0; i<itsLen; i++)
    		temp[i] = itsString[i];
    	for (unsigned short j = 0; j<rhs.GetLen(); j++, i++)
    		temp[i] = rhs[i-itsLen];
    	temp[totalLen]='\0'; What is this doing here? is it assigned the value of totalLen, meaning the the two strings to temp or what?
    	*this = temp;
    }

    It adds \0 to the end of the character array. This is known as the terminating character. All strings have this at the end of them.

    Ok, besides that isn't temp[totalLen]='\0' doing something else besides that? I mean temp[totalLen] isn't this assigning the value of totalLen to temp or something or is this giving it access to the string at totalLen? Something anything else besides the fact that it's adding the new line character to it.

    It's saying that the character at position totalLen in the string is equal to the string-termination character.
