What is the purpose of a slice in Go?

A. To store key-value pairs.

B. To represent a resizable array.

C. To define a block of code to be executed later.

D. To perform arithmetic operations.

Correct Answer is :

B. To represent a resizable array.

Explanation

In Go, a slice is a data structure that represents a resizable and dynamically sized array. Slices provide a more flexible way to work with sequences of data compared to arrays, as they can grow or shrink as needed. Slices are widely used in Go for managing collections of data, such as lists or sequences. Option A is incorrect because slices do not store key-value pairs; that's the purpose of maps in Go. Option C is incorrect because defining a block of code to be executed later is typically done using functions or closures, not slices. Option D is incorrect because slices are not used for performing arithmetic operations.
