Remove extra white space from inside a C string?

Question

I have read a few lines of text into an array of C-strings. The lines have an arbitrary number of tab or space-delimited columns, and I am trying to figure out how to remove

Answer 1

If I may voice the "you're doing it wrong" opinion, why not just eliminate the whitespace while reading? Use fscanf("%s", string); to read a "word" (non whitespace), then read the whitespace. If it's spaces or tabs, keep reading into one "line" of data. If it's a newline, start a new entry. It's probably easiest in C to get the data into a format you can work with as soon as possible, rather than trying to do heavy-duty text manipulation.
