ios - Will app lose the NSUserDefault data on over the air installation? -


this question has answer here:

will app lose nsuserdefaults values when on air installation?

  1. no app installed in device
  2. install app version 1.0 on air , saving values in nsuserdefaults
  3. install app version 1.0 on air again out deleting app.
  4. will lose nsuserdefaults values because of installing same version?

whatever have in nsuserdefaults remains in device/system. never gets deleted when upgrade app on uninstalling or manually deletion removed.

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.
