Question

How to combine these 2 main functions of c++ files in 1 main class?

//SinglyLinkedList

int main() {
SinglyLinkedList<std::string> list;
list.Add("Hello");
list.Print();
list.Add("Hi");
list.Print();
list.InsertAt("Bye",1);
list.Print();
list.Add("Akash");
list.Print();
if(list.isEmpty()){
cout<<"List is Empty "<<endl;
}
else{
cout<<"List is not empty"<<endl;
}
cout<<"Size = "<<list.Size()<<endl;
cout<<"Element at position 1 is "<<list.get(1)<<endl;
if(list.Contains("X")){
cout<<"List contains X"<<endl;
}
else{
cout<<"List does not contain X"<<endl;
}
cout<<"Position of the word Akash is "<<list.IndexOf("Akash")<<endl;
cout<<"Last Position of the word Akash is "<<list.LastOf("Akash")<<endl;
list.RemoveElement("Akash");
cout<<"After removing Akash from the list "<<endl;
list.Print();
return 0;
}

//DoublyLinkedList

int main() {
DoublyLinkedList<std::string> list;
list.Add("Hello");
list.Print();
list.Add("Hi");
list.Print();
list.InsertAt("Bye",1);
list.Print();
list.Add("Akash");
list.Print();
if(list.isEmpty()){
cout<<"List is Empty "<<endl;
}
else{
cout<<"List is not empty"<<endl;
}
cout<<"Size = "<<list.Size()<<endl;
cout<<"Element at position 1 is "<<list.get(1)<<endl;
if(list.Contains("X")){
cout<<"List contains X"<<endl;
}
else{
cout<<"List does not contain X"<<endl;
}
cout<<"Position of the word Akash is "<<list.IndexOf("Akash")<<endl;
cout<<"Last Position of the word Akash is "<<list.LastOf("Akash")<<endl;
list.RemoveElement("Akash");
cout<<"After removing Akash from the list "<<endl;
list.Print();
return 0;
}

/*
//changed name so that it will be eassy to understand if the variable of SinglyLinkedList or DoublyLinkedList
also due to can't have two variable of same name
Changed the message which will print to not have doubt regarding operation of different list 
*/
int main() {
SinglyLinkedList<std::string> s_list;
s_list.Add("Hello");
s_list.Print();
s_list.Add("Hi");
s_list.Print();
s_list.InsertAt("Bye",1);
s_list.Print();
s_list.Add("Akash");
s_list.Print();
if(s_list.isEmpty()){
cout<<"Singly list is Empty "<<endl;
}
else{
cout<<"Singly list is not empty"<<endl;
}
cout<<"Size of Singly list = "<<s_list.Size()<<endl;
cout<<"In Singly list Element at position 1 is "<<s_list.get(1)<<endl;
if(s_list.Contains("X")){
cout<<"Singly list contains X"<<endl;

DoublyLinkedList<std::string> d_list; //changes
