Study Notes

C++ Programming Fundamentals

  • main is the entry point of any C++ application.
  • Mid-level programming languages, such as C++, exhibit strong abstraction and mid-range access to memory and the operating system.
  • Pointers are variables.
  • Code blocks are located within curly brackets/braces, opened by { and closed by }.

Data Types

  • unsigned short data type has a minimum value of 0.
  • bool data type has a maximum value of 1.
  • Explicit data types are strong-typed data types.
  • Implicit data types are variables that may not declare their data types.
  • short data type can have a maximum value of 32768.

Flowcharts and Pseudocodes

  • Flowcharts are created using word-processing applications.
  • SET...AS is a keyword in pseudocodes that indicates a value being stored to a temporary storage from any source excluding user entry.
  • INPUT is a classification of technical work items for all user entries.
  • IF...THEN...END is a category in pseudocodes that deals with decision making.

Loops and Control Statements

  • Condition is the phase in looping statements where the looping statements are evaluated.
  • Iteration is not a special variable that controls the flow of loops.
  • break statement ends the execution of the entire loop.
  • Statement where it terminates the execution of the current iteration is called break statement.

Functions and OOP

  • CALL is a keyword that calls user-defined functions.
  • A typical initialization of a counter is set to 0.
  • Return type is a part of a function that indicates the final value of the function.
  • Object-Oriented Programming (OOP) is a programming centered in the use of objects.
  • Polymorphism is a principle of OOP that deals with different variations of the same method.

Development Tools and Platforms

  • MinGW presents a minimalistic approach in presenting tools and libraries necessary to develop applications for Microsoft Windows.
  • IDE is needed to be enabled to compile our selected compiled programming language to executables.
  • Minimalist GNU for Windows (MinGW) is the preferred compiler for C++ in Windows x86 architecture.
  • GitHub is an open-source community's most famous and most used online version control repository since 2016.
