A small demostration of the usage of std::vector to create a simple management system to manage 3D vectors. I used this in a game hack for CS

#include <windows.h>
#include <stdio.h>
#include <fstream.h>
#include <vector>

using namespace std;

struct vec
{
	float h;
	float f;
	float r;
};

#define VEC_INDEX_MAX 32
vector<vec> Vecs[VEC_INDEX_MAX];

#define VECS 6
Functions to add, list and erase, as in every management system
Code:
void func_vec_add(int index, float x, float y, float z)
{
	vec v;
	v.h = z;
	v.f = x;
	v.r = y;	 *
	if(index<=VECS){
		Vecs[index].push_back(v);
	}
}

void func_vec_clear(int index)
{
 * *if(index == -1){
 * * * for(int i=0;i<=VECS;i++)
		 * Vecs[i].clear();
 * *}
	else if(index>=0&&index<=VECS){
 * * * * * *Vecs[index].clear();
 * *}
}

void func_vec_list(int index)
{
	cout << "\n";

	if(index == -1){

		int cantidad=0;

		for(int i=0;i<=VECS;i++)
		for(vector<vec>::iterator si = Vecs[i].begin(); si != Vecs[i].end();++si)
		{
			 cantidad++;
			 printf("Height: %f Forward: %f Right: %f\n",si->h,si->f,si->r);
		}

		if(cantidad==0)
			cout << "There are no elements !" << endl;
	}

	else
	{
		if(index<=VECS){
		 * for(vector<vec>::iterator si = Vecs[index].begin(); si != Vecs[index].end();++si)
		 * {
				printf("Height: %f Forward: %f Right: %f\n",si->h,si->f,si->r);
		 * }
		}
	}
}
Main function, used for testing purposes
Code:
int main(){

	func_vec_add(0, 100, 200, 0.61f);
	func_vec_add(1, 100, 200, 0.98f);
	func_vec_add(2, 100, 200, 0.59f);
	func_vec_add(3, 100, 200, 0.15f);
	func_vec_add(4, 100, 200, 0.00f);
 * * * *func_vec_add(5, 100, 500, 1.00f);
	func_vec_add(6, 100, 900, 2.00f);

	//func_vec_list(0);
	func_vec_list(-1);

	func_vec_clear(-1);

	func_vec_list(-1);

	cin.get();
	return 0;
}
