Question

I’m trying to create a array of structs, but define it’s size later, like so:

struct xy{

int x;
int y;
};

int main(){
    xy pos;
    int size = 10;
    pos = new xy[size];
    pos[0].x = 5;
}

But I can’t get it to work no matter what I try. Also I don’t want to use a vector for this, so please don’t say I should.

Answer 1

new returns a pointer:

int main(){
    xy* pos;
    int size = 10;
    pos = new xy[size];
    pos[0].x = 5;
}
