Main Function

WateringPlan.C

#include <iostream.h> #include <string.h> #include "Plant.h" #include "PlantList.h" using namespace std; int main() { PlantList plants; string name; int frequency; while (cin >> name && cin >> frequency) { plants.add(Plant(name, frequency)); } plants.print_plan(); }

While cin >> name normally returns cin to permit a concatenation of operations, it is in the given context

implicitly converted to void * (an unspecified pointer) with the support of a conversion operator of cin,

and subsequently implicitly converted to bool.

This works in a way that the condition evaluates to true if both read operations succeed and to false otherwise.

Plant(name, frequency) creates an anonymous object of type Plant that is destroyed after the execution of the statement using it finishes.
