Instruction: Include FULL Screenshot that display your code and output on Apex Exercise 1 Create an anonymous block that declare the variable v_test_date as a DATE data type. Initialize v_test_date with the date 2025-01-31. Output the string "The test date is" concatenated with the value of v_test_date. The output is "The test date is 2025-01-31". Exercise 2 Create an anonymous block that declares the variable v_today as a DATE data type. Initialize v_today with the system date. Output the string "Today is" concatenated with the value of v_today. If SYSDATE was January 31, 2025, the output would appear as "Today is 2025-01-31. Exercise 3 Create an anonymous block that declares the variable v_default_date as a DATE data type. Do not initialize v_default_date but set the default date as the system date. Output the string "The default date is" concatenated with the value of v_default_date. If SYSDATE was January 31, 2025, the output would appear as "Today is 2025- 01-31." Exercise 4 Create an anonymous block containing a constant called TAX_RATE initialized with the value 0.13 (13 per cent). In the executable section, output the string "The tax rate is" concatenated with the value of TAX_RATE as a whole number. The output is "The tax rate is 13 percent."
