    What does this line of code mean?

    Hi

    I'm very much a C++ newbie and I'm trying to read some code I've been given, but I can't find what this line means:

    Code:
    list< int > result;
    'result' seems to be a class of some sort, but I don't understand this syntax at all. Does anyone have any ideas?

    list is a template class, which means you can have lists of whatever you want.
    In this case, it's a list of ints.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    The C++ language has certain features like variables and arrays. An array can be used to store more than one value. C++ also provides you with other "containers" that can store more than one value. One of those "containers" is called a list. The code:
    Code:
    list< int > result;
    declares a list named "result" that will contain ints. It uses a different syntax, but it is similar to how you would declare an integer array:
    Code:
    int myArray[10];
    However, with a list, you don't have to specify the size. The size of the list changes automatically as you add ints to it.
