I'd like to have a vector of queues in my program but my compiler ( Microsoft Visual C++ 6.0 ) isn't allowing it.  What is wrong with this syntax?

void sysGen(vector<queue<int>>, vector<queue<int>>,
         vector<queue<int>>);

The problem is ">>" - the compiler mistakenly interprets that as the right-shift operator ("max-munch"). make your code read

void sysGen(vector<queue<int> >, vector<queue<int> >,
        vector<queue<int> >);  // note the spaces!

Oh, or you could also

typedef queue<int> int_queue;

void sysGen(vector<int_queue>, vector<int_queue>,
        vector<int_queue>);

or

typedef queue<int> int_queue;
typedef vector<int_queue> vector_of_int_queues;

void sysGen(vector_of_int_queues, vector_of_int_queues,
        vector_of_int_queues);
