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

The video tutorial guides students through building a triangle calculator using structs. It begins with an introduction to the task, followed by correcting a minor error. The formula for calculating the area of a triangle is explained, and students are instructed to write a triangle struct with base and height as unsigned integers. They then create a triangle instance, calculate its area, and are encouraged to try the exercise independently. The lesson concludes with motivational remarks.

What is the primary task in this exercise?

• To build a square calculator

• To build a triangle calculator

• To correct spelling mistakes

• To learn about circles

Which formula is used to calculate the area of a triangle?

• Base times height divided by 2

• Base times height

• Height times width divided by 2

• Length times width

What values should the triangle struct take?

• Base and height

• Radius and diameter

• Length and width

• Height and width

What are the base and height values set to in the new triangle struct?

• Base: 5, Height: 15

• Base: 20, Height: 40

• Base: 10, Height: 30

• Base: 15, Height: 25

What is the final step after creating the triangle struct?

• Print the calculated area

• Print the perimeter

• Print the base value

• Print the height value
