The following data items will be recorded each time a student successfully logs on to the school network: Data item Example data Student ID "CJL404" Host ID "Lib01" Time and date "08:30, June 01, 2021" The Student ID is six characters long. The other two data items are of variable length. A single string will be formed by concatenating the three data items. A separator character will need to be inserted between items two and three. For example: "CJL404Lib01<separator>08:30, June 01, 2021" Each string represents one log entry. A programmer decides to store the concatenated strings in a 1D array LogArray that contains 2000 elements. Unused array elements will contain an empty string.

1. (a)Suggest a suitable separator character and give a reason for your choice. Character Reason[2]
2. (b)The choice of data structure was made during one stage of the program development life cycle. Identify this stage.[1]
3. (c)A function LogEvents() will: • take a Student ID as a parameter • for each element in the array that matches the Student ID parameter: o add the value of the array element to the existing text file LogFile o assign an empty string to the array element • count the number of lines added to the file • return this count. Write pseudocode for the function LogEvents().[7]
