How would you modify the main() function to print a 6-layer cake for a 4th birthday?

The correct answer involves setting the variable for age to 4, which signifies that it is the child's 4th birthday. However, you need to set the number of layers in the cake to 6, as specified in the prompt, to ensure that the cake meets the desired specifications for the celebration.

In Kotlin, you would typically declare these variables in the main() function, perhaps as follows:

fun main() {

val age = 4

val layers = 6

println("For a $age birthday, we need a $layers-layer cake.")

}

By defining the age as 4, you accurately reflect the child's birthday, while setting the layers to 6 meets the requirement for a cake designed for that special occasion. This approach ensures the output matches the intended celebration details.

Other options do not properly satisfy the requirements of printing a cake for a 4th birthday. For instance, setting the age to any value other than 4 would not accurately represent the birthday age, and using incorrect types for these values (like strings instead of integers) would lead to issues when you attempt to perform any arithmetic or formatted output. Leaving the code unchanged would also not fulfill the request to modify it
