c++ - Qt - Return an Array Of Array Of qint32 -


this question has answer here:

i have in main :

void main() {      qint32 led[32][32];      led = init_all(led); }

i have this, don't work :

qint32** init_all(qint32 led[32][32]) {      //set 0      return led; }

i return correctly led.

you need pass led pointer (or reference in case of c++) init_all. otherwise, copy passed subroutine, not, want. btw, should start learning c or c++ before starting qt. need basic knowledge of programming language before starting qt.

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
