how do i add remove and display using an array or struct???

If you have an array of structs, initialize all the structs in the array to some value you know to be non-valid. You can put a constructor in the struct:

struct example{
int x;
int y;
int z;
example():x(-1),y(-1),z(-1){}

// for output using cout

friend ostream& operator <<(ostream& o, example e)
{
o<<e.x<<endl<<e.y<<endl<<e.z<<endl;
return o;
}

};


for the output you can set it to only output when x != -1 y != -1 etc


To remove them from the array

[1][2][3][4][5][6][7]

say you want to get rid of 4

shift 5 6 and 7 left so the new result will look like
1 2 3 5 6 7 and make sure to set the old 7 to all -1's
