Code 2.2 is for a program that demonstrates variable declarations and the use of literal and symbolic constants. The program prompts the user to input his/her weight (in grams) and year of birth. The program then calculates and displays the user’s weight (in pounds) and his/her age during the RIO Olympics year (2016). Type the code, compile (F9), and run (F10) Code 2.2. Save it as varsandconts.c. Answer the following:
1. What are the two symbolic constants used?
2. Show two methods of defining a symbolic constant named MAXIMUM that has a
value of 100. Provide the correct syntax.
3. Give an advantage of using a symbolic constant over a literal constant.
