* QtNetwork (examples) - update the second download manager exampleTimur Pocheptsov2017-10-025-41/+71
| | | | | | | | | | | | | | | | | It's the one that is more complex - with a text-based 'progress-bar' and queueing (for some, probably educational, reason) of requests. Changes: - update the C++ syntax (mem-initializers, range for, etc.) - new-style headers - redirects should not result in creating an empty file. Since we have no UI, and this example is already complex enough, settle for just reporting the redirect and removing the empty file.

* QtNetwork (examples) - update network download managerTimur Pocheptsov2017-10-021-26/+32
| | | | | | | | | | | | | Mainly 'modernizing' - use <c...> c-library includes (<stdio.h> -> <cstdio>), add appropriate using directive; minor fixes in formatting + removal of a hated double negation (aka ifndef QT_NO_NOTHING). Also, as our rules ('how to write examples') suggest - replace too many inclusion directives with module-level headers. Basic redirects handling - do not create empty files for redirected requests (or even files with some useless html).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The square root of a sum of squares is easier to read and should be computed more accurately if done for us by hypot(). Variables set only once should be set as an initializer and declared const, to make clear this is what's happening. Loop variables can be local to loops. Adding a value to, or subtracting one from, a multiple of itself just multiplies it be one plus (or minus) the multiplier; assigning the result to the same variable is clearer as a *= (especially when the factors are now overt numeric constants). An array of 16k floats all updated in locksteck to the same value can be replaced by a single float that holds that value. Simple things should not be needlessly made more complicated - especially in example code, which should be pedagogic. Change-Id: Idab585cd7df1399c250d4b9f1396a085ae8f3864 Reviewed-by: hjk <hjk@qt.io>

Replaced math.h with qmath.h in places that defined a fall-back in case math.h omits it (it's not in the C++ standard, although M_PI is in POSIX); or removed this entirely where it wasn't used. Reworked some code to reduce the amount of arithmetic needed, in the process; e.g. pulling common factors out of loops. Revised an example's doc to not waste time talking about using a six-sig-fig value for pi (which we no longer do) - it really wasn't relevant, or anything to be proud of; nor did the doc mention its later use.
