A-level Computing/CIE/Fundamental Problem-solving and Programming skills/Data representation

Specification link Data types select appropriate data types for a problem solution use in practical programming the data types that are common to procedural high-level languages: integer, real, char, string, Boolean, date (pseudocode will use the following data types: INTEGER, REAL, CHAR, STRING, BOOLEAN, DATE, ARRAY, FILE) show understanding of how character and string data are represented by software including the ASCII and Unicode character sets Arrays use the technical terms associated with arrays including upper and lower bound select a suitable data structure (1D or 2D array) to use for a given task use pseudocode for 1D and 2D arrays (pseudocode will use square brackets to contain the array subscript, for example a 1D array as A[1:n] and a 2D array as C[1:m, 1:n]) write program code using 1D and 2D arrays write algorithms/program code to process array data including: sorting using a bubble sort searching using a linear search. Files show understanding of why files are needed use pseudocode for file handling: OPENFILE <filename> FOR READ/WRITE/APPEND // Open file (understand the difference between various file modes) READFILE <filename>,<string> // Read a line of text from the file WRITEFILE <filename>,<string> // Write a line of text to the file CLOSEFILE // Close file EOF() // function to test for the end of the file write program code for simple file handling of a text file, consisting of several lines of text Cambridge International state that using the With command in Python is acceptable.
