David, Mason, and Scarlett are working on a fun coding project for their computer science class. They're having a lively debate about the difference between writing out a variable's value and its label. Can you jump in and help them clear up the confusion?
There is no difference, both display the same information
Writing out the value displays the actual data, like the score Scarlett got in the test, while writing out the label displays the variable name, like 'Scarlett_Score'
Writing out the value and the label are the same thing
Writing out the value displays the variable name, like 'David_Age', while writing out the label displays the actual data, like David's age
