Question

a) True
b) False

Answer 1

In Kotlin, variables can be declared using either the val or var keyword. By default, it is recommended to declare variables using the val keyword. However, the var keyword can be used if necessary.

Step-by-step explanation:

In Kotlin, variables can be declared using either the val or var keyword. The val keyword is used for declaring variables whose values cannot be changed once assigned, making them immutable. On the other hand, the var keyword is used for declaring variables whose values can be changed, making them mutable.

By default, it is recommended to declare variables using the val keyword whenever possible. This promotes immutability and helps in writing safer and more predictable code. However, if you anticipate the need to modify the variable's value later, you can use the var keyword.

Therefore, the statement By default, you should strive to declare all variables in Kotlin with the val keyword. Change it to var only if necessary. is true.
