How to extend the below code to collect the all entry.score
and not just keep the most recent one?
The code I have right now is:
std::unordered_map<std::string, float> container;
int main() {
// some code
for (auto entry : entries)
container[entry.name] = entry.score;
}
How to extend it to keep all entry.score
whilst avoiding copy?:
std::unordered_map<std::string, std::vector<float>> container;
//vectors need to be updated using .push_back(entry.score)
int main() {
// some code
for (auto entry : entries)
container[entry.name] = ; //missing connection
}
container[entry.name]
returns a std::vector<float>&
. std::vector
exposes push_back
, which inserts an element into the vector.
Therefore you can do:
container[entry.name].push_back(entry);
