How do I iterate over a Constant Vector?

Question

I have a vector of Student which has a field name.

I want to iterate over the vector.

void print(const vector& students)
    {
            


        

Answer 1

Use const_iterator instead. An iterator allows modification of the vector, so you can't get one from a const container.

Also, the idiomatic way to write this loop uses it != students.end() instead of < (though this should work on a vector).
