21:49, 5 February 2023 Bmackenty talk contribs created page Vector (Created page with "In computer science, a vector is a data structure that represents an ordered, dynamic array of elements. It's similar to an array, but it has the advantage of being able to dynamically resize its size as elements are added or removed. A vector typically stores elements of the same data type, and provides operations to add, remove, or access elements. The size of a vector can change as elements are inserted or deleted, and it automatically reallocates memory as needed. T...")
21:32, 5 February 2023 Bmackenty talk contribs created page Unsigned integers (Created page with "Unsigned integers are a type of integer data type that can only represent non-negative whole numbers (positive numbers and zero). They are represented using a fixed number of bits, typically 8, 16, 32, or 64 bits, depending on the computer architecture and the programming language. Unlike signed integers, unsigned integers do not use a sign bit to indicate the sign of the integer value. Instead, all bits are used to represent the magnitude of the integer value. This all...")
21:31, 5 February 2023 Bmackenty talk contribs created page Signed integers (Created page with "Signed integers are a type of integer data type that can represent both positive and negative whole numbers. They are represented using a fixed number of bits, typically 8, 16, 32, or 64 bits, depending on the computer architecture and the programming language. The most significant bit (MSB) is used to indicate the sign of the integer value, with a value of 0 representing a positive number and a value of 1 representing a negative number. The remaining bits are used to r...")
21:28, 5 February 2023 Bmackenty talk contribs created page Scalar type (Created page with "Scalar type in programming refers to a data type that can represent a single value, as opposed to a more complex data structure such as an array or object. Scalar types can include primitive data types such as integers, floating-point numbers, and strings, among others. In many programming languages, scalar types are also referred to as simple or atomic data types. A scalar type is a general term used to describe a data type that can represent a single value. A primitiv...")
10:11, 4 February 2023 Bmackenty talk contribs created page Struct (Created page with "A "struct" is a composite data type that groups together zero or more values with different data types into a single unit. It is used to represent a single object made up of multiple pieces of data, such as a point in 2D space (x, y), or a record in a database (name, address, age, etc.). Each piece of data within a struct is called a "field". Structs can be found in many programming languages, including C, C++, and Rust. They provide a way to bundle related data into a s...")
10:07, 4 February 2023 Bmackenty talk contribs created page Enum (Created page with "An "enum" (short for "enumerated type") is a data type that consists of a set of named values. It is used to represent a set of distinct, named values in a program, making it easier to read, maintain, and avoid bugs. For example, in a program that tracks the days of the week, an enum could be used to represent the days of the week instead of using raw integers or strings. Enums can be found in many programming languages, including Rust, C++, and C#.<ref>ChatGPT</ref> I...")
13:58, 3 February 2023 Mr. MacKenty talk contribs created page Stack memory (Created page with "Stack memory is a region of computer memory used for storing da,ta that has a short lifespan such as function call frames, function parameters, and local variables. It operates on a Last-In-First-Out (LIFO) principle, where the most recently added data is the first to be removed. This makes stack memory ideal for storing temporary data and function calls, as the data is automatically cleaned up when the function returns. In a typical computer program, the stack is used...")
13:57, 3 February 2023 Mr. MacKenty talk contribs created page Heap memory (Created page with "Heap memory is a region of computer memory used for dynamic allocation of objects at runtime. It is a dynamic area of memory where blocks of memory are allocated and deallocated dynamically as needed, in contrast to the stack memory, where memory is allocated and deallocated in a last-in-first-out (LIFO) manner. Objects stored in the heap have a longer lifetime than objects stored in the stack, as heap-allocated objects persist until they are explicitly deallocated or un...")
10:40, 29 January 2023 Bmackenty talk contribs created page Binary classification model (Created page with "A binary classification model is a type of machine learning model that is used to classify data into two distinct classes or categories. These models are trained to differentiate between two possible outcomes, such as "yes" and "no", "true" and "false", or "positive" and "negative". Examples of binary classification problems include spam detection, sentiment analysis, and medical diagnosis. Common algorithms used in binary classification include logistic regression, deci...")
