Worked Solution & Example Answer:A string variable called month has been assigned the value ‘April’ and another string variable called year has been assigned the value ‘2019’ as shown below - Scottish Highers Computing Science - Question 2 - 2019
Step 1
DECLARE shortDate INITIALLY month[0:3] + year[2:4]
Answer
To assign the value 'Apr19' to the variable shortDate, we use substring operations. The expression month[0:3] extracts the first three characters of the string 'April', which yields 'Apr'.
Next, year[2:4] extracts the last two characters of the year string '2019', giving us '19'.
Concatenating these two substrings together gives us:
shortDate = month[0:3] + year[2:4]
Therefore, after execution, shortDate will hold the value 'Apr19'.
Step 2
Alternative Method: Using SUBSTRING Functions
Answer
An alternative approach can use the substring or similar functions depending on the programming language. For example:
shortDate = substring(month, 0, 3) + substring(year, 2, 2)
This achieves the same result, and shortDate will also contain 'Apr19'.
