Indexing vector value inside vector dreived class

This has got to be a simple C++ issue, but how do you index a vector value inside vector dreived class:
Does that work?
I need to compare a value in the vector for an insertion so I can keep my list in a sorted condition. I am feeding these values to my sorting compare function like this:
Where "this" is a vectorPtr derived class. This is inside a class method.
this[index]

Here is some code I tested under GCC (testVector.cc):
#include <stdio.h> #include <vector> class vclass : public std::vector<int> { public: void print(); }; void vclass::print() { int index; for(index = 0; index < size(); index++) { int val = operator[](index); printf("this[%d]: %d\n",index,val); } } int main(int argc, char **argv) { // Create instance of vector based class. vclass tvclass; tvclass.push_back(5); tvclass.push_back(3); tvclass.push_back(1); tvclass.push_back(-1); tvclass.print(); }Compile like this:
