Thread: Quick check on reading in + using strings

Hi

I've been writing some C programs with the scanf funciton and wondered if there was an easier way to input data. I need functions which can:

1. Identify set areas in strings (e.g. is the [x]th letter in a 1?)
2. Read in strings (e.g. if I want to enter 1234 into an array num[4] it can place each number into each array space, so num[0]=1..... num[3]=4)
3. Count the length of a string (e.g. the string "cisfun" is 6 characters long)

4. I need to know how spaces and new-line characters (presing the enter key) are handled

I'm only using the command line.

Thanks!

Just a note: Except in special cases, 32 and 10 should not be used to represent space and newline in C. Instead, ' ' and '\n' are preferred, for a couple of reasons: No magic numbers, so it's obvious what they stand for; portable to non-ASCII systems.

If you're writing, say, a charset converter, then it's absolutely necessary to know the values of various characters in various charsets; but for a simple C program, portable constructs should be used.
