Question

My use case:

map<string, Car> cars;
bool exists(const string& name) {
  // somehow I should find whether my MAP has a car
  // with the name provided
  return false;
} 

Could you please suggest the best and the most elegant way to do it in C++? Thanks.

Answer 1

Sure, use an iterator

map<string,Car>::const_iterator it = cars.find(name);
return it!=cars.end();
