Object initialized with random numbers

I'm pretty new to c++ and oo, so this is probably something pretty silly. This is all in the code right after my include statements.

enum ObjType { CUBE, CONE, };
typedef struct {
   ObjType type;
   float x;
   float y;
   float z;
   int selected;
} object;

static object objects[] =
{ 
    { CUBE, rand()%11-4, rand()%-10-5, rand()%-65-55, 0},
    { CONE, rand()%11-4, rand()%-10-5, rand()%-65-55, 0},
}

I make a call to srand, passing in the current time, in my main method. However, this is generating the same random numbers every time the program is wrong. What am I not understanding?
