Equivalent of scanf

[Michael Koehmstedt]

I'm having trouble figuring out how to do formatted console input, something
like C scanf() or C++ templated stream input. Unfortunately, console input
isn't covered in much detail in TDPL book. There doesn't appear to be much
discussion about the standard library at all, which was a bit disappointing.

But anyway, what different ways are there to properly do input from the
console? Fetching a string with readln() is easy enough, but how could I
fetch, say, an integer value? Conversely, what is the preferred method for
converting string into integer or floating point values?

Thanks,
Michael
