auto removeByIndex =
[]<class T>(std::vector<T> &vec, unsigned int index)
{
// This is the meat & potatoes
vec.erase(vec.begin() + index);
};
// Then you can throw whatever vector at it you desire
std::vector<std::string> stringvec = {"Hello", "World"};
// Will remove index 1: "World"
removeByIndex(stringvec, 1);
// Vector of integers, we will use push_back
std::vector<unsigned int> intvec;
intvec.push_back(33);
intvec.push_back(66);
intvec.push_back(99);
// Will remove index 2: 99
removeByIndex(intvec, 2);
