A-LevelComputer ScienceFile HandlingMay/June 2024Paper 2 Q27 Marks
A program uses a global 1D array of type string and a text file. An algorithm that forms part of the program is expressed as follows: • copy the first line from the file into the first element of the array • copy the second line from the file into the second element of the array • continue until all lines in the file have been copied into the array. Stepwise refinement is applied to the algorithm. Outline five steps for this algorithm that could be used to produce pseudocode. Assume there are more elements in the array than lines in the file. Do not use pseudocode statements in your answer.
