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.
