Homework #2

due: Monday Feb 19, 2024

Each student is responsible for doing their own work. You are welcome to discuss this on slack or in class, but when it comes to writing the code, you are expected to write it yourself (and not just copy from someone).

Note: using ChatGPT or similar AI tools to write your code is not allowed.

1. In this repo you'll find a C++ program called numbers.cpp. As written, it will read in numbers from the user and add them to a vector. This will continue until the user enters a negative number. At that point, the program will return the sum of the input numbers.

   Your task: modify this program to return the average and the standard deviation of the numbers.

   Aside: In the above code, we did our sum by looping over the data directly, But we can instead use std::accumulate(). This function is described here: https://en.cppreference.com/w/cpp/algorithm/accumulate

2. Consider a vector initialized as:

   std::vector<double> vec{0.1, 10.0, -2.9, 5, 12.2, 0.0, -103.2};
   

   Let's see how to use some of the functions in the algorithm header.

   Write a code to create this vector and then loop over elements to find the maximum element in the vector. Do the same to find the minimum element in the vector. Be sure to output the result to the console.

   Now repeat this, but use std::max_element (https://en.cppreference.com/w/cpp/algorithm/max_element) and std::min_element (https://en.cppreference.com/w/cpp/algorithm/min_element) to get the same result.
