Lab 7

This document contains a C++ implementation of a templated Vector class that allows for the creation, modification, and scalar multiplication of a vector. The main function demonstrates the usage of this class by creating a vector of integers, modifying an element, and multiplying the vector by a scalar. The class includes methods for displaying the vector contents and handling out-of-bounds errors during modifications.
