How to use arrays and slices in Go

The video tutorial explains the concepts of arrays and slices in the Go programming language. It covers the characteristics and limitations of arrays, such as their fixed size and homogeneous data type requirement. The tutorial then introduces slices, highlighting their flexibility in size and the ability to append elements. It also discusses helper functions like Len and Cap for managing slice lengths and capacities, and touches on memory management considerations. Finally, the video covers multidimensional arrays and slices, providing examples of their syntax and usage.

What is a key characteristic of arrays in Go?

• They can hold elements of different data types.

• They can dynamically change size.

• They have a fixed size.

• They are always multidimensional.

How can you create a slice in Go?

• By using curly braces.

• By using a fixed size array.

• By slicing an existing array or slice.

• By using a pair of square brackets with a dimension.

Which function is used to add elements to a slice in Go?

• insert()

• append()

• add()

• push()

What does the 'cap' function in Go determine?

• The current number of elements in a slice.

• The maximum number of elements a slice can hold.

• The index of the last element in a slice.

• The data type of elements in a slice.

How are multidimensional arrays accessed in Go?

• Using a single index.

• Using two or more indexers.

• Using a special function.

• Using a loop.
