Description : Copies elements from the range [first, last)
, to another range beginning at d_first
, replacing the elements which satisfy specific criteria by a new_value
.
Example:
auto isOdd = [](int i) {
return ((i%2) == 1);
};
std::vector<int> origin {1, 2, 3, 4, 5};
std::vector<int> destination;
// Copy elements to destination replacing elements that return true for isOdd by 0
std::replace_copy_if(origin.begin(), //first
origin.end(), //last
std::back_inserter(destination), //d_first
isOdd, //condition
0 //new_value
);
// origin is still {1, 2, 3, 4, 5}
for (auto value : origin) {
std::cout << value << " ";
}
std::cout << std::endl;
// destination is {0, 2, 0, 4, 0}
for (auto value : destination) {
std::cout << value << " ";
}
std::cout << std::endl;
