#SUMMARY:
=> Use ${} to surround variables and calculations in the text of print statements. For example: ${age} where age is a variable.
=> Create a variable using the val keyword and a name. Once set, this value cannot be changed. Assign a value to a variable using the equal sign. Examples of values are text and numbers.
=> A String is text surrounded by quotes, such as "Hello".
=> An Int is a whole positive or negative number, such as 0, 23, or -1024.
=> You can pass one or more arguments into a function for the function to use, for example: fun printCakeBottom(age:Int, layers:Int) {}
=> Use a repeat() {} statement to repeat a set of instructions several times. For example: repeat (23) { print("%") } or repeat (layers) { print("@@@@@@@@@@") }
=> A loop is an instruction to repeat instructions multiple times. A repeat() statement is an example of a loop.
=> You can nest loops, that is, put loops within loops. For example, you can create a repeat() statement within a repeat() statement to print a symbol a number of times for a number of rows, like you did for the cake layers.
#Summary of using function arguments: To use arguments with a function, you need to do three things:
=> Add the argument and type to the function definition: printBorder(border: String)
=> Use the argument inside the function: println(border)
=> Supply the argument when you call the function: printBorder(border)
