c++ - trouble checking for overlap in a 2-D array of chars -


i having trouble part of program takes dynamically allocated object called userrect , checks overlapping on array of chars arranged in shape of rectangle. other rectangles rect[0] , rect[1] randomly placed on imaginary grid in console window.

rect[0] prints out '0' rect[1] prints out '1' userrect prints out '#' if no overlap present. userrect prints out '+' @ each char in array overlapping object.

the object userrect movable w,a,s,d keys. supposed happen when user moves userrect object , overlaps rect object. each character overlaps replaced '+'.

the program not printing '+' when userrect overlapping rectangle. can point out causing this?

here sample of code:

    bool isoverlapping(rect const & r) const     {         return !(min.x >= r.max.x || max.x <= r.min.x             || min.y >= r.max.y || max.y <= r.min.y);     }   int main() {     srand(time(null));     // initialization     rect * userrect;     const int rectsize = 5;     rect rect[rectsize];     const int array_size = 13;  // size of userrect     userrect = new rect();      // set     rect[0].setrandom(rect[0]);     rect[1].setrandombypointer(& rect[1]);     userrect->setmin(7, 5);     userrect->setmax(10, 9);     //rect0.setmin(10, 2);     //rect0.setmax(14, 4);     //rect1.setmin(1, 6);     //rect1.setmax(5, 15);     int userinput;          {         // draw         rect[0].draw('0');         rect[1].draw('1');           (int = 0; < array_size; i++)         {             if (userrect->isoverlapping(rect[i]))             {                 userrect->draw('+');             }             else userrect->draw('#');         } 

i have figured out wrong. problem in loop. if userrect within boundaries of rect[0] not within bounds of rect[1] userrect->draw('#'); overwrite userrect->draw('+'); operation executed before it. thank guys help.
