Kerry,
1. Loop round reading a line at a time and interpreting the columns. You
want to store the 3 columns into variables - sex, age and tattoo_count.
fscanf is good for this - do a "man fscanf"
2. Check the sex for values other than M or F. What about lower case m or f
?
3. Storing the answers in an array. Not sure if this is a great idea - how
many lines could the file contain ? How do you know ahead of time how big
the array needs to be ?
4. I would just copy the answers straight to their destination without
storing them.
HTH,
John
