hello friend, why random generator always show same number ?```
for(int j=1;j<s2+1;j++)
{

    qsrand(time(NULL));

dizi[j]=(qrand()%32);

}

output :
3
3
3
3
or
28
28
28
28

qsrand

You're using deprecated functions. You should rather use http://doc.qt.io/qt-5/qrandomgenerator.html

@veysel.olgun said in random number:

qsrand(time(NULL));

seeds rand with the seconds since the epoch.

I would think you end up seeding again in a much quicker time than 1 sec -> next rand is again seeded and calculated the same way -> same "random"-number

i understand now , when i write

      qsrand(time(NULL));
  dizi[j]=(QRandomGenerator::global()->generate()%32);

it works fine

thank you all
