Algorithm - replace()

원형)

template <class ForwardIterator, class T>
  void replace (ForwardIterator first, ForwardIterator last,
                const T& old_value, const T& new_value);

의미)

[Iterator first, Iterator last)사이에 있는 데이터 들에 대해서 old_value와 같은 데이터들을 new_value값으로 바꿉니다.

void Print(const std::vector<int>& target)
{
    for (std::vector<int>::const_iterator iterPos = target.begin(); iterPos != target.cend(); iterPos++)
        std::cout << *iterPos << ' ';
    std::cout << std::endl;
}
 
void main()
{
    std::vector<int> vector = { 1,3,5,7,4,1,2,5,1 };
 
    std::cout << "Vector--->"; Print(vector);
    std::replace(vector.begin(), vector.end(), 1, 99);
    std::cout << "Vector--->"; Print(vector);
