Computing Science

1. Software Design and Development

   • Computational Structures
     • Assigning vales to variables
     • Using arithmetic operations e.g. +, -, *
     • Pre-defined fucntions
     • Selection constructs
       • IF Statement
     • Iteration and repetition constructs
       • Fixed loops
       • Conditional loops
   • Data Types and Structures
     • Arrays
       • number[5]
     • String, character
     • Numeric
       • Integers
         • 1, 55, -23
       • Reals (singles)
         • 0.6, -14.25, 30.123
     • Boolean
       • TRUE, FALSE
   • Testing and Documenting
     • Testing - e.g. enter a number between 1 and 10
       • Normal - e.g. 2,3,4,5,6,7,8,9
       • Extreme - e.g. 1, 10
       • Exceptional - e.g. 0, 11, A, #
