In Kotlin, Write code that declares a nullable Int and sets its value, then declares a nullable Double and uses the safe call operator to sets its value to null if the nullable Int was null, else to the result of casting the Int to a Double. Write code that that declares a nullable Int and sets its value, then declares a nullable Double and uses the safe call operator and the Elvis operator to sets its value to 0.0 if the nullable Int was null, else to the result of casting the Int to a Double

The interest paid on a savings account is compounded daily. This means that if you start with startbal dollars in the bank, at the end of the first day you’ll have a balance ofstartbal * (1 + rate/365)dollars, where rate is the annual interest rate (0.10 if the annual rate is 10 percent). At the end of the second day, you’ll havestartbal * (1 + rate/365) * (1 + rate/365)dollars, and at the end of n days you’ll havestartbal * (1 + rate/365)ndollars. Write a program that processes a set of data records, each of which contains values for rate, startbal, and n and computes the final account balance.

2. Create a program that computes and displays a game character's attack speed at a certain level. Use the formula below. Formula: Current attack speed = Base attack speed * (1 + (Bonus attack speed % * (Level - 1) The variable for level should be of int type. The bonus attack speed % should be converted to decimal (divide by 100) before multiplying by the level. For example, if the user enters 4% for the bonus attack speed, the formula will use 0.04 instead of 4. Round the current attack speed to the nearest two (2) decimal places. Sample Output: Enter the base speed of the attack:0.65 Enter the bonus attack speed %:4 Enter the level:10 The character/s current attack speed is 0.88 ...
