Algorithms and flowcharts (Yet another C++ assignment).

Code:

SENTENCE Empty = {"", "", "", "", "", "", "", ""};
Line = Empty;

Okay good, I was on the right track then!

And as for the if explanation, that makes all kinds of sense now. And as for the GetWord function, all I did was remove the error functions because they were (ironically) giving me errors, I don't think the program recognized them at all. I'm going to assume that there won't be two of the same indicator entered.

Code:

void GetWord(istream & inF, int & linepos, int & wordpos, string & word)
{
    char ch;            //Variable to check for indicators.
    int num;            //Position numbers before position check.
    linepos = -1;        
    wordpos = -1;        //These have not been given values yet and 0 is part of the sentinel: -1 is thus used.

    //Read two numbers in unknown order and with possible whitespace between them.
    do
    {
        if (ch == '+' || ch == '-') //Checks for position indicator before number.
        {
            inF >> num;                //Number comes after indicator, number is being read next.
            if (ch == '+')
            {
                linepos = num;        //Gets line position if indicator is +.
            }
            else
            {
                wordpos = num;        //Gets word position if indicator is -.
            }
        }
        else if (ch == ':')            //If no position indicator, checks for the start of the sentinel character, which is :.
        {
            // read the next 3 characters and if they are :0:0: then exit, otherwise exit with format error message - not coded yet
        }
    } while (linepos < 0 || wordpos < 0);

    inF >> word;                //Read word after positions.

    return;
}
