java - how to store string data into integer array from sqlite for android -


i want convert sqlite data integer array.

public integer[] getch() {          sqlitedatabase database = this.getreadabledatabase();         cursor cursor = database.rawquery("select sum(sales) sales group outlet_code order ordered_date", null);         // string[] array = new string[crs.getcount()];         int columnindex = 3;         integer[] in = new integer[cursor.getcount()];          if (cursor.movetofirst())         {             (int = 0; < cursor.getcount(); i++)             {                 in[i] = cursor.getint(columnindex);                 cursor.movetonext();             }         }         cursor.close();         return in;     }

i need result in following format:

int[] income = { 2000,2500,2700,3000,2800,3500,3700,3800, 0,0,0,0};  integer[] income =  controller.getch();

i'm getting error :

couldn't read row 0, col 3 cursorwindow. make sure cursor initialized correctly before accessing data it

why using columnindex = 3, sql query return 1 column i.e sum(sales), should set columnindex value 0

try this

public integer[] getch() {      sqlitedatabase database = this.getreadabledatabase();     cursor cursor = database.rawquery("select sum(sales) sales group outlet_code order ordered_date", null);     // string[] array = new string[crs.getcount()];     int columnindex = 0;     integer[] in = new integer[cursor.getcount()];      if (cursor.movetofirst())     {         (int = 0; < cursor.getcount(); i++)         {             in[i] = cursor.getint(columnindex);             cursor.movetonext();         }     }     cursor.close();     return in; }

hope helps

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.
