Question

I am working on a very big and old C++ project. The word “vector” has been used all over the place. I am now trying to add new functionality to the project utilizing STL vector. This is not working. In addition, I am only allowed to modify specific sections of the code, so I can not change their use of “vector”.

Is there a way to rename STL vector and use it?

Answer 1

Use C++ namespaces.

#include <vector>

// note the absence of `using namespace std;` line

int main() {
    // note the `std::` qualification
    std::vector<int> x;

    // ...
}
