Whilst working my way through "The ANSI C Programming Language" I came across an exercise on chapter one that I just don't understand. The exercise is:
Write a program detab that replaces tabs in the input with the proper
number of blanks to space to the next tab stop. Assume a fixed set of tab stops, say every
n columns. Should n be a variable or a symbolic parameter?
Could someone please explain to me what this is asking? Thank you
