Study Notes

Computer Program

  • A computer program consists of a set of instructions performing a specific task.
  • Programs are essential for computers to function, executed by a central processing unit (CPU).

Reasons for Program Development

  • Programs may be created for creative expression.
  • They can satisfy personal curiosity or generate new knowledge.
  • Programs often address specific problems for individuals, organizations, or society.

Iterative Process

  • Iteration involves repeating a process to create various outcomes or to reach a specific goal.
  • Each repetition is termed an "iteration" and builds upon the previous results.

Debugging

  • Debugging is the process of identifying and eliminating errors in computer hardware or software.

Program Documentation

  • Software documentation includes written or illustrated materials explaining software operation or usage.
  • It serves different purposes for individuals in various roles within software engineering.

Development Principles

  • Incrementally adding tested segments to existing programs does not necessarily lead to the correct development of larger programs.
  • Regular consultation and communication with users are crucial for effective program problem-solving.
  • Collaboration is advantageous in program development.
  • Program instructions are executed in a sequential order.
  • Processes utilize memory, a CPU, and handle input/output operations.

Function vs. Procedure

  • Functions must return a value, while returning values for procedures is optional.
  • Functions can accept only input parameters, whereas procedures can manage input/output parameters.
  • Functions can be utilized within procedures, but procedures cannot be called from functions.

Benefits of Procedures

  • Procedures help simplify writing and maintaining programs.

Parameters

  • A parameter is a measurable factor defining a system's operation conditions.

Functions with Parameters

  • Functions allow for generalized solutions by utilizing parameters instead of duplicating code.

Application Program Interfaces (APIs)

  • APIs consist of routines and protocols essential for software application development.
  • They define interactions between software components and are foundational for GUI programming.

Data Structures

  • An array is a data structure housing elements identified by one or more indices.
  • The position of array elements is calculable from their index using a mathematical formula.

Boolean Logic

  • Boolean refers to algebraic notation for representing logical propositions in computing.
  • It operates with two values: true and false.

Mathematical Expressions

  • In programming, expressions are combinations of values, constants, variables, operators, and functions interpreted to produce another value.

Logical Operators

  • Logic operations manipulate Boolean values and are fundamental in computer science, named after mathematician George Boole.
