In C++ ______ operator is used while declaring references.
struct Player
{
string firstName;
string lastName;
int hits;
int runs;
};
int main()
{
Player p = { "Jackie", "Robinson", 1518, 947 };
Player team[24];
Player *tPtr = team;
team[0] = p;
// INSERT CODE HERE
}
The statement tPtr = team+9; will assign the same memory address to tPtr as the statement tPtr = &(team[9]);
