C++ (Cpp) validate_std_vector_index Examples

Example #1

std::vector<T> head(const std::vector<T>& sv,
                    size_t n) {
    if (n != 0)
        validate_std_vector_index(sv, n, "head");
    std::vector<T> s;
    for (int i = 0; i < n; ++i)
        s.push_back(sv[i]);
    return s;
}

Example #2

 std::vector<T> tail(const std::vector<T>& sv,
                     size_t n) {
   if (n != 0)
     validate_std_vector_index(sv, sv.size() - n + 1, "tail");
   std::vector<T> s;
   for (int i = sv.size() - n; i < sv.size(); ++i)
     s.push_back(sv[i]);
   return s;
