Question

This is my instruction:

* Place all entitities into a set of simulation objects
Use the set template for c++11
Items are of type Entity *
*/

/* Run the simulation for 100 steps */
/* iterate through your set of entity objects
Invoke "step()" on each one.
Each type of entity should update appropriately.
Each type of entity should display appropriately, once every 10 steps.
*/

entity has 3 "Children", buyer, seller, and retailer. This is a diamond problem inhertiance, where retailer is the child of buyer and seller, and buyer and seller are the direct children of entity. This is what I have so far.

set Entity;

for (int i = 0, i < 100, i++) {

Entity.insert( "?????????");

Entity.step(); <<<----- Entity should be of type seller, buyer, or retailer, not just entity.

if ( i % 10 == 0 ) {

cout << ???? <<< end1;

}

thanks for any help

Explanation / Answer

std::set <Entity *> entitySet;
entitySet.insert(willieWonka);
entitySet.insert(momAndPop);
entitySet.insert(jackNjill);
entitySet.insert(cust1);
entitySet.insert(cust2);
entitySet.insert(cust3);
entitySet.insert(cust4);

//entity has 3 "Children", buyer, seller, and retailer. This is a diamond problem inhertiance, where retailer is the child of buyer and //seller, and buyer and seller are the direct children of entity. This is what I have so far.

for (int i = 0; i < 100;i++) {

for(set<Entity*>::iterator iterator = entitySet.begin(); iterator!=entitySet.end(); ++iterator){

(*iterator)->step(); // <<<<<<won't work for some reason "step not declared in scope" [it's in entity and it's derived classes]

if ( i % 10 == 0) {
(*iterator)->list(); // <<<<<<won't work for some reason "step not declared in scope" [it's in entity and it's derived classes]

}

}
