Explain three factors that can/should affect how code reads.
1. One factor of how the computer reads code is placement, for example, if you place a System.out.println("Hello"); and then System.out.println("World") the console will first print out Hello and then prints out World. 2. Another factor on how a computer can read code is semi-colons. For example, if you add a semi-colon to the end of your line of code it means to run that line of code. 3. A final way is that a computer can read variables, for example, if you have an int statement you can call the statement from wherever in the code program.
