Image Resolution and PPI in Computer Graphics

In this video, we're going to discuss Image Resolution and PPI (Pixels Per Inch) concepts in Computer Graphics. In the display screen, the number of horizontal and vertical pixels is called Resolution and the Image Resolution is specifically concerned with the total number of pixels (Height * Width of Image). Moreover, the Image Resolution is generally described in PPI (Pixels Per Inch). These two are quite important to understand to learn Computer Graphics. So, let's get started now.

C++ Tutorial: Functions Prototypes / Declarations

Prototypes help you declare your functions so that you can use them throughout the program and outside the scope of other functions. Function Prototypes help organize code in C++. Function Prototypes are helpful in C++. Prototypes / Declarations will help you organize your program.

Functions Prototypes can be also be known as declarations some people will use these two interchangeably.

C++ Tutorial: Functions with Parameters and Examples

This will be an introduction to C++ Functions for Beginners. Functions can help organize code or help with repetitive code. A programmer gets to define their own functions with whatever operations they want to perform in the Function. Functions are a way to organize code in C++.

This C++ Tutorial is for Beginners and intended for learning the concepts of C++. Functions are fundamental structure in C++. They are a great thing to know how to use and Functions are one of the building blocks of C++.

C++ Tutorial: Arrays Introduction for Beginners

This will be an introduction to C++ Arrays for Beginners. Arrays can help a user define multiple data types that can be accessed by a index. We'll take user input in and then let the user know what they supplied. This is a C++ Tutorial for Beginners.

C++ Tutorial: Break, Continue, and Goto

C++ Tutorial for Beginners Ep#15 we learn about Break, Continue, and Goto statements in C++. Break is commonly used in switch case and continue to skip over a iteration in a For/While Loop. It can cause more issues in your program than it's worth. Break and Continue are used extensively in certain cases in C++.

00:00 Intro
00:11 Syntax 
00:58 Continue Example

C++ Tutorial: Variable Scope

C++ Tutorial for Beginners Ep#14 where we learn about Variable Scope and and how to use Variable Scope in C++. Variable Scope in C++ comments can also help delete unnecessary variables once you are finished with them called temp variables. Everything between { } are considered local scope and anything outside th main function or any other function can be considered a global scope variable.
 

00:00 Intro
00:10 Local Scope
00:46 Global Scope
01:25 Local Scope Variable Example
02:25 Second Example (w/ Error)

C++ Tutorial: Single & Multi-line Comments

C++ Tutorial for Beginners Ep#13 where we learn about Multi-Line and Single Line Comments and how to use them in C++. Comments can help with reminding yourself what you've created in a program. Comments are important tools in a C++ program that serve as reminders. Multi-Line C++ comments can also take out a portion of code temporarily for testing. Today we'll explore Single & Mult-Line Comments in depth and understand how and where to use them in C++.

When using Single & Multi-Line comments in our C++ code they are great for reminders, explanations, commenting out code, and mentions. Don’t over complicate the comments because no one wants to read paragraphs of information for simple lines of code. Assume that the person reading knows C++ and can read the code try sticking to a brief overview. Much like a email subject. If it’s a complex piece of code with many lines then you can go into more depth.

C++ Tutorial: While & Do While Loops

C++ Tutorial for Beginners Ep#12 where we learn about While & Do While Loops and how to use them in C++. While loops can help with running a block of statements until a condition is false. While & Do While are important tools in a C++ program. Do While Loops run a block of statements at least once even if the condition is false the first time through. While loops can help with running a block of statements until a condition is false. Today we'll explore While Loops in depth and understand how to program one ourselves.

When using While & Do While Loops we can run our code until a condition is false in our parentheses. This helps execute a block of code indefinitely until the condition is not met. An example would be running a program until a user wants to exit the program with a While/Do While. This gives us great capability of interacting with the user of the program until they are ready to exit out. We'll learn about this and much more in today's episode of C++ While & Do While Tutorial for Beginners.

C++ Tutorial: For Loops

C++ Tutorial for Beginners Ep#11 where we learn about For Loops and how to use them in C++. For loops can help with iterative processes. Execute a line of code with a For Loop a specific amount of times or until a condition is met. They can help condense code and allow the program to iterate over certain objects. C++ For Loops are a great tool for programming. Today we'll explore For Loops in depth and understand how to program one ourselves.

When using For Loops we have three options. Created initialized values, create a condition, and update a value in our loop. Each time through our For Loop we can increate our iterator that way we can do a specific function a certain amount of time before breaking out of the For Loop. Use For Loops where you know how many times you need to iterate over a specific set of statements/functions/etc.

C++ Tutorial: #define Macros and Macro Functions

C++ Tutorial for Beginners Ep#10 where we learn about the defining Macros/Macro Functions with the #define preprocessor directive in C++. Marcos can help user define various constants / functions that will be filled in by the preprocessor. They can help condense code into one-liners and allow the program to reuse already know function or values. C++ macros can be used with existing preprocessor directives.This C++ Tutorial is for Beginners is intended for learning the concepts of C++. Use Visual Studio Code or any text editor to follow along. Make sure to subscribe so you can follow the series.


When using preprocessor directives and C++ Macros you can define which portion of the code should be compiled. This is good for build/debug compilations. Where you might not want to include debug statements in the final build. A Macro with #ifdef / #ifndef could help you achieve this without having to write two separate files. Let's explore Macros and some of their uses together in this #define Macros and Macro Functions episode of C++ Tutorial for Beginners.

C++ Tutorial: Switch Case for Beginner

C++ Tutorial for Beginners Ep#9 where we learn about the Switch Case flow control. Switch Cases are used with non-changing values in C++ and want to control the flow of the program. Switch Case statements can also help you condense if/else if statements in some cases. This C++ Tutorial is for Beginners is intended for learning the concepts of C++. Use Visual Studio Code or any text editor to follow along. Make sure to subscribe so you can follow the series.

Switch Case statements help with organization and flow control in your program. They make sense where there are a bunch of known options such as arguments that a user will pass into the program. If you already know what the possible arguments are then a switch case can be used to go through each individual argument and make a decision on what to do next. Switch Cases are similar in a sense to if / else if / else. Let's explore how.
