for example
I was wondering how you can use the same function like that. The above wont work. And yes it is defined:Code:for(t = 0; t<100; t++){ sands[t] = new sand(10,t) }
I might have to explain my problem better...Code:class Dot { private: int x, y; int xVel, yVel; public: Dot(int x,int y); void fall(); void move(); void show(); void setxy(int xx,int yy); }; Then those functions are further defined
One way is to define a function object:
Then you use the function object in conjunction with std::generate_n(), e.g.,Code:class MakeDot { public: MakeDot(int x) : x(x), y(0) {} Dot operator()() { return Dot(x, y++); } private: int x; int y; };
Code:std::vector<Dot> sands; std::generate_n(std::back_inserter(sands), 100, MakeDot(10));

In my first example...
Where would I define the "sands" thing?
Um, you would define it before you use it.
On a hunch, are you a Java programmer? I have a feeling that you are unnecessarily and incorrectly using new due to such a background.
