Category: A Level

11.1 Programming Basics
1 Implement and write pseudocode from a given design presented as either a program flowchart or structured English

2 Write pseudocode statements for:
• the declaration and initialisation of constants
• the declaration of variables
• the assignment of values to variables
• expressions involving any of the arithmetic or logical operators input from the keyboard and output to the console

3 Use built-in functions and library routines

11.2 Constructs

1 Use pseudocode to write:
• an ‘IF’ statement including the ‘ELSE’ clause and nested IF statements
• a ‘CASE’ structure
• a ‘count-controlled’ loop:
• a ‘post-condition’ loop
• a ‘pre-condition’ loop

2 Justify why one loop structure may be better suited to solve a problem than the others

11.3 Structured Programming

1 Define and use a procedure

2 Explain where in the construction of an algorithm it would be appropriate to use a procedure

3 Use parameters

4 Define and use a function

5 Explain where in the construction of an algorithm it is appropriate to use a function

6 Use the terminology associated with procedures and functions

7 Write efficient pseudocode
