A-LevelComputer ScienceProgramming FundamentalsOct/Nov 2021Paper 2 Q510 Marks
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.
