C++ vector 많이 쓰이는 것들

value -> index 찾는 법

vector<int> v{3,4,5,6,8,1};
int value = 5;
vector<int>::iterator iter = find(v.begin(), v.end(), value); // *iter == 5
int idx = distance(v.begin(), iter); // 2
// vector[idx] == value

못찾으면 iter == v.end()

할당하는법

vector<int> v;
v.assign(5, 2); // v == {2, 2}, v.assign(size, value)

vector<int> v2;
v2.assign(v.begin(), v.end());

vector<int> v3{1,2,3,4,5};

vector<int> v4(3, 6); // v4 == {6, 6, 6}, (size, value)

vector<int> v5(5); // v5 = {0, 0, 0, 0, 0}

vector<int> v6(v.begin(), v.end());

vector의 최대, 최솟값

vector<int> v{2,3,5,4,8,1};
vector<int>::iterator iter = max_element(v.begin(), v.end());
// 최솟값은 min_element(v.begin(), v.end());
