How to return DMU on copies of string fragments?

Question

Arrays

void func(char *str){
  char *outStr = new char[256];
  for(int i = 3; i < strlen(str)-3; i++){
    int j = 1;
    while(str[i-j] == str[i+j])
      j++;
    if(str[i-j] != str[i+j]){
      cout << "\n";
    }
    if(j > 3){
      for(int k = i-j+1; k < i+j; k++){
        cout << str[k];
      }
     }	
  }
}
int main(){
  SetConsoleCP(1251);
  SetConsoleOutputCP(1251);
  char str[256];
  cout << "Введите строку \n"; 
  cin.getline(str,256);
  func(str);
  getchar();
}

The function searches the string for symmetry.
