Three Programs

Create a program (or programs) which show how the language you picked (Kotlin) works with the following:

1. I/O
2. Data Structures
3. Control Structures

Report Card Generator

Accepts a file sample.grades where each line is an assignment in the format: <course name>: <grade>. The program iterates through the file and computes the average and letter grades for all courses listed in sample.grades.

Language structures used include:

• Iterable unpacking
• Implicit type arguments
• Null safety and propagation (as in courses[course]!!.add(grade))
• Iteration
• Actions (as in file.forEachLine)
• Pattern matching (simple example using when expression)

Kotlin library features used include:

• File I/O
• Standard I/O
• String conversions
• Mutable maps and lists
