Description : Copies elements from the range [first, last), to another range beginning at d_first, replacing the elements that matches old_value by a new_value.
Example:
std::vector<int> origin {3, 5, 3, 1, 2, 3};
std::vector<int> destination;
// Copy elements to destination replacing elements that are 3 by 0
std::replace_copy(origin.begin(), //first
origin.end(), //last
std::back_inserter(destination), //d_first
3, //old_value
0 //new_value
);
// origin is still {3, 5, 3, 1, 2, 3}
for (auto value : origin) {
std::cout << value << " ";
}
std::cout << std::endl;
// destination is {0, 5, 0, 1, 2, 0}
for (auto value : destination) {
std::cout << value << " ";
}
std::cout << std::endl;
