An algorithmis a set of instructions that are followed to solve a problem. It's a computer's thought process.
An argumentis a way to provide more information to a function. The function can then use that information as it runs, like a variable (For more info on variables, see below.)
Arrays are containers that hold variables; they're used to group together similar variables. You can think of arrays like shelves at a pet store. The array would be the shelf, and the animals in cages are the variables inside.
Arithmetic operators are essential in almost every application, especially in games. If a game character earns experience, it needs to be added to the total earned. If an arrow hits an enemy, the damage the enemy takes needs to be calculated.
Assignment operators (+=, -=, *=, /=) are operators that combine variable assignments (=) with arithmetic operators. They serve as a shortcut when coders have to perform an operation that changes the value of a variable. If a rock falls on a game player's head, health needs to be subtracted from their total, and so on.
Augmented reality (AR) is an interactive experience where digital objects are placed in a real-world environment in real time. While virtual reality creates a completely artificial environment, augmented reality uses the existing real-world environment and overlays new information on top of it. Pokémon Gois a popular example, blending the real worl...
Autonomous robot, self-driving car, and delivery bot are all terms used to describe robots that navigate their environments using sensors with little to no human interaction.
A binary number is a computer's way to represent information. Computers process millions of 1's and 0's a minute using different rules to interpret them as numbers, letters, operators, and everything else put into a computer.
With block-based coding, programming "blocks" fit together like puzzle pieces. When you code with blocks, you take the first block you want the program to execute and attach it to another block, and so on.
C++ is a low-level yet versatile programming language. Beginnners who master this language will be able to solve complex problems and understand how programs work. Related: Online C++ tutoring for kids and teens
Mar 7, 2024 · We take a deep dive into the most common programming errors with examples and tips on how to avoid and mitigate these errors to improve your code.
Feb 21, 2024 · Operators in programming are symbols or keywords that represent computations or actions performed on operands. Operands can be variables, constants, or values, and the combination of operators and operands form expressions.
There are seven meanings listed in OED's entry for the adjective unguarded. See ‘Meaning & use’ for definitions, usage, and quotation evidence.
Aug 10, 2021 · Coding is a subset of programming, which entails the logical reasoning, analysis, and planning out a sequence of instructions for a computer program or application before any coding is done. Programming is the bigger picture in the process.
