C++ Range-based for Loop

신기하기도 하고 혁명인 것 같다

vector<double> temps {87.2, 77.1, 80.0, 72.5};

double average_temp {};
double running_sum {};

for (auto temp : temps)
	running_sum += temp;

average_temp = running_sum / temps.size();

auto

for (auto c : "Frank")
	cout << c << endl;

result

F
r
a
n
k

example

vector<double> temperatures{ 87.9, 77.9, 80.0, 72.5 };
double average_temp{};
double total{};
for (auto t : temperatures)
	total += t;
average_temp = total / temperatures.size();

cout << "total : " << total << endl;
cout << "average_temp is : " << average_temp << endl;
