C で std::remove() を使用して文字列から特定の文字を削除するにはどうすればよいですか?

#include <iostream>
#include <algorithm>

int main() {
  // Get user input for phone number
  std::string phone;
  std::cout << "Enter phone number: ";
  std::cin >> phone;

  // Characters to remove
  char chars[] = "()- ";

  // Remove the specified characters using std::remove()
  for (unsigned int i = 0; i < strlen(chars); ++i) {
    phone.erase(std::remove(phone.begin(), phone.end(), chars[i]), phone.end());
  }

  // Output the modified phone number
  std::cout << "Cleaned phone number: " << phone << std::endl;

  return 0;
}

void removeCharsFromString(std::string &str, char *charsToRemove) {
  for (unsigned int i = 0; i < strlen(charsToRemove); ++i) {
    str.erase(std::remove(str.begin(), str.end(), charsToRemove[i]), str.end());
  }
}

int main() {
  std::string phone;
  std::cout << "Enter phone number: ";
  std::cin >> phone;

  char chars[] = "()- ";

  removeCharsFromString(phone, chars);

  std::cout << "Cleaned phone number: " << phone << std::endl;

  return 0;
}
