IGCSE (CIE) Computer Science Revision for paper 21/22/23 Part B only with answers

11.1 Programming Basics 11.2 Constructs 11.3 Structured Programming 11.1 Programming Basics Implement and write pseudocode from a given design presented as either a program flowchart or structured English Write pseudocode statements for: • the declaration of variables and constants • the assignment of values to variables and constants • expressions involving any of the arithmetic or logical operators input from the keyboard and boutput to the console. Use built-in functions and library routines Any functions not given in the pseudocode guide will be provided String manipulation functions will always be given 11.2 Constructs 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 Justify why one loop structure may be better suited to solve a problem than the others **11.3 Structured Programming ** Define and use a procedure Explain where in the construction of an algorithm it would be appropriate to use a procedure. Use parameters: A procedure may have none, one or more parameters and A parameter can be passed by reference or by value. Define and use a function Explain where in the construction of an algorithm it is appropriate to use a function. A function is used in an expression, e.g. the return value replaces the call. Use the terminology associated with procedures and functions: including Procedure / function header, procedure / function interface, parameter, argument, return value Write efficient pseudocode
