This information contains a name, a difficulty level and 9 scores. The problem I am having is that my while loop isn't looping. It's only reading the first full line of the file. Any suggestions? Thanks in advance! Angie int main() { // declare variables int SIZE; double difficulty, score, total_score; string name; ifstream infile; infile.open("MP6dive.dat"); if (!infile) { cout << "Trouble opening data filen" ; return 1; } infile >> SIZE; infile >> name >> difficulty; total_score = 0; while(infile) { cout << name << setw( << difficulty << setw(7); int i; for(i=0; i <= JUDGES; i++) { infile >> score; cout << score << " "; total_score = score + total_score; } double final_score = total_score * difficulty; cout << final_score << endl; infile >> name >> difficulty; } infile.close(); return 0; } // end main Back to top Victor Bazarov Guest Posted: Wed Jul 30, 2003 6:11 pm    Post subject: Re: while loops "Angie" <ahurlbut (AT) NOSPAM (DOT) umich.edu> wrote...

You only told it to read the first full line of the file. Instead of if(!infile)... try this: while(infile) { infile >> name >> difficulty; cout << name << difficulty; total_score = 0; for(int i = 0; i < 9; i++) { infile >> score; cout << score; total_score += score; } } -- Posted via http://dbforums.com Back to top jwtroll05 Guest Posted: Thu Jul 31, 2003 4:31 pm    Post subject: Re: while loops Yeah...sorry. I viewed the original message in an internet newsgroup reader and it saw the < signs and the > signs as html tags or something and a lot of the code was missing. Ignore my previous post. -- Posted via http://dbforums.com Back to top Angie Guest Posted: Fri Aug 01, 2003 1:45 pm    Post subject: Re: while loops Angie wrote: Quote: The problem I am having is that my while loop isn't looping.

(Loops and I have a very strained relationship...)
