Rust Programming 2023 - A Comprehensive Course for Beginners - Solution - Write Methods and Structs in Rust

This video tutorial guides viewers through creating a triangle struct in Rust, writing a method to calculate its area, and debugging common errors. It starts with an introduction to methods and structs, then demonstrates how to create a triangle struct with base and height properties. The tutorial continues with writing a method to calculate the area using the self keyword, creating an instance of the triangle, and using the method to compute the area. Finally, it addresses common errors and concludes with a summary of the learning objectives.

What is the primary focus of the initial part of the tutorial?

• Understanding Rust's memory management

• Learning to write methods and structs in Rust

• Debugging Rust programs

• Exploring Rust's concurrency model

What is the significance of using an uppercase letter for struct names in Rust?

• It helps in distinguishing structs from variables

• It is a requirement by the Rust compiler

• It improves the performance of the code

• It is used to indicate private structs

Which keyword is used to access the properties of a struct within a method in Rust?

• instance

• struct

• self

• this

What is the formula used to calculate the area of a triangle in the tutorial?

• base * height / 2

• base / height

• base * height

• base + height

What is the purpose of creating a new instance of the triangle struct?

• To modify the existing struct

• To test the method with different values

• To demonstrate inheritance in Rust

• To create a copy of the struct

What values are assigned to the base and height of the new triangle instance?

• Base: 15, Height: 25

• Base: 5, Height: 15

• Base: 20, Height: 40

• Base: 10, Height: 30

What is the expected output when the area method is run on the new triangle instance?

• 100

• 150

• 200

• 250
