How do I convert vector of strings into vector of integers in C++?

Question

I have a vector of strings. Need help figuring out how to convert it into vector of integers in order to be able to work with it arithmetically. Thanks!

#include

#include

#include 

using namespace std;

int stringToInteger(const std::string& s)
{
    return boost::lexical_cast(s);
}

int main(int /*argc*/, char* /*argv*/[])
{
    vector vectorOfStrings;

    // ..

    vector vectorOfIntegers;
    std::transform(vectorOfStrings.begin(), vectorOfStrings.end(), std::back_inserter(vectorOfIntegers), stringToInteger);

    // ..
}

You can replace the implementation of stringToInteger(..) with your preferred conversion function.
