Answer / Gulwaiz Akhter
In Kotlin, both `var` and `val` are used to declare variables. The main difference lies in their mutability behavior: n1. `val`: A `val` is immutable and its value cannot be changed after it is initialized.n2. `var`: A `var` can be reassigned a new value after it is initialized.
