Kotlin Basics Preparation

Overview

As you now know, there are some core things that every programming language has. You’ve seen the syntax already during the scavenger hunt, but now it’s time to think a bit more deeply about what all the syntax was doing.

Basic Learning Objectives

Before class, you should be able to explain the following in Kotlin:

Basic types
Collections
Control flow
Functions

Advanced Learning Objectives

After class, you should be able to:

Write Kotlin using basic types, collections, control flow, and functions

Readings

To achieve the pre-class learning objectives, you should read the following sections in the Kotlin tour:

Hello World
Basic Types
Collections
Control Flow
Functions - Up to but not including Lambda expressions

Checks

You should submit answers to the following on the Gradescope assignment linked through Moodle (note that you can and should try typing up and running your answers). You may upload them in the same file or different files and the name of the files doesn’t matter.

The code below computes a student’s GPA, but some lines are in the wrong order. Put the lines in the correct order. The output of this program should be:
```
 Student’s GPA: 3.65
```
Given a list of letter grades from a student’s transcript, the function calculateGPA computes a student’s GPA based on Carleton’s grading system, but some parts are missing. Fill in the blanks for the code for the function calculateGPA. (main is already complete.) The output of this program should be:
```
 Student’s GPA: 3.25
 Student’s GPA: 2.42
 Student’s GPA: 2.17
```
