Dear Sir,

I dont understand the below error in following Program. I'm trying to return objects from member function.


35 C:\...\Untitled1.cpp no match for 'operator=' in 'r = (&my)->Travel::add(your)'
note C:\...\Untitled1.cpp:6 candidates are: Travel& Travel::operator=(const Travel&)

    cout <<"!!! Total traveling Record !!!"<<endl;
    r.show();
    system("pause");
}

There are a couple of problems with function return types:
 
 
    int get(){
should be
 
 
    void get(){
because the function does not return a value.

The opposite problem is in function add(), it is declared as void, but it should return a value of type Travel
Change 
 
 
    void add(Travel p){
to 
 
 
    Travel add(Travel p){
