\n

Development methodologies<\/h3>\n<\/td>\n

Describe and implement the phases of an iterative development process: analysis, design, implementation, testing, documentation, and evaluation, within general programming problem-solving.<\/td>\n<\/tr>\n
\n

Analysis<\/h3>\n<\/td>\n

Identify the purpose and functional requirements of a problem that relates to the design and implementation at this level, in terms of:<\/p>\n
    \n
  • inputs<\/li>\n
  • processes<\/li>\n
  • outputs<\/li>\n<\/ul>\n<\/td>\n<\/tr>\n
\n

Design<\/h3>\n<\/td>\n

Identify the data types and structures required for a problem that relates to the implementation at this level, as listed below.<\/p>\n

Describe, identify, and be able to read and understand:<\/p>\n

    \n
  • structure diagrams<\/li>\n
  • flowcharts<\/li>\n
  • pseudocode<\/li>\n<\/ul>\n

    Exemplify and implement one<\/strong> of the above design techniques to design efficient solutions to a problem.<\/p>\n

    Describe, exemplify, and implement user-interface design, in terms of input and output, using a wireframe.<\/td>\n<\/tr>\n

\n

Implementation (data types and structures)<\/h3>\n<\/td>\n

Describe, exemplify, and implement appropriately the following data types and structures:<\/p>\n
    \n

  • Boolean<\/li>\n
  • 1-D arrays<\/li>\n<\/ul>\n<\/td>\n<\/tr>\n
\n

Implementation (computational constructs)<\/h3>\n<\/td>\n

Describe, exemplify, and implement the appropriate constructs in a high-level (textual) language:<\/p>\n
    \n
  • expressions to assign values<\/li>\n
  • expressions to return values using arithmetic operations (addition, subtraction, multiplication, division, and exponentiation)<\/li>\n
  • expressions to concatenate strings<\/li>\n
  • selection constructs using simple conditional statements with <,>, \u2264, \u2265, =, \u2260 operators<\/li>\n
  • selection constructs using complex conditional statements<\/li>\n
  • logical operators (AND, OR, NOT)<\/li>\n
  • iteration and repetition using fixed and conditional loops<\/li>\n
  • pre-defined functions (with parameters):\n
      \n
    • random<\/li>\n
    • round<\/li>\n
    • length<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n
