示例1: evolve_virus
/*
* modifies the attribute of this virus
*/
bool Virus::evolve_virus(Zone zone){
// we first check if we want to evolve the virus or not
// uses randomness, the total number of infected people, level of pollution and healthcare
double prob;
prob = ((rand() % 100 + 1.0)/100.0) * this->current_infected/zone.get_initial_population()
* zone.get_location().pollution * (1.0 - zone.get_location().healthcare);
if ((rand() % 100 + 1.0)/100.0 > prob) {
return false;
}
else { // evolve virus and return true
// firstly, we want to make this virus immune to past cures and vaccines
int i = zone.has_virus(this->name);
// use i to access previous vaccine and cure for this virus, modify them
zone.get_vaccines()[i].set_id(1);
zone.get_cures()[i].set_id(1);
