    How to declare a list in another list???

    Ex: I declare a function in class List:
    Code:
    void Copy(List<List<Entry>> &des,List<Entry> source);
    In using function:

    Code:
    List<int> list1;
    list1.insert(position1,item1);
    list1.insert(position2,item2);
    list1.insert(position3,item3);
    List<List<int>> listtemp;
    list2.copy(listtemp,list1);
    I want to declare a list that their entries are a list( type of integer)...
    How to declare it...when i use above declaration..compiler informs that: missing ',' before listtemp..Why?? please help me....Thanks very much....

    >List<List<int>> listtemp;
    Code:
    List<List<int> > listtemp;
    It's subtle, but notice the space between the two >'s. C++'s parsing grammar recognizes >> as the bitwise right shift operator, not two adjacent closing delimiters for nested template argument lists. You disambiguate it by separating them with whitespace.
    My best code is written with the delete key.
