android - Difference between setSupportActionBar and setActionBar -


so trying use toolbar actionbar in app. trying use setsupportactionbar() method in fragment hosted activity extends class extends appcompatactivity. reason i'm not able getactivity().setsupportactionbar() @ all, can getactivity().setactionbar(). problem setsupportactionbar() accepts android.support.v7.widget.toolbar setactionbar() accepts android.widget.toolbar. causes app restricted devices using lollipop.

a side issue i've found when trying change theme of toolbar dark 

app:theme="@style/themeoverlay.appcompat.dark"

it doesn't work.

getactivity() has class activity, if activity kind of subclass appcompatactivity. have cast getactivity(), call 

((appcompatactivity)getactivity()).setsupportactionbar()

for theme-problem should post details have put style-definition or rather put in separate question.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
