C++ algorithm replace_copy_if() 函数

示例

创建一个向量的副本，并将所有包含字母"o"的值替换为"Toyota"：

bool has_o(string item) {
  return item.find('o') != string::npos;
}

int main() {
  vector<string> cars = {"Volvo", "BMW", "Ford", "Mazda"};
  vector<string> newcars(4);
  replace_copy_if(cars.begin(), cars.end(), newcars.begin(), has_o, (string)"Toyota");
  for (string car : newcars) {
    cout << car << "
";
  }

  return 0;
}
