10 Words Every New Programmer Must Know
01. String
A string is a sequence of characters, typically used to represent text in programming. It can include letters, numbers, symbols, and whitespace. In most programming languages, strings are enclosed in quotation marks (either single ' or double " quotes).
02. Integer
An integer is a whole number that can be either positive, negative, or zero, without any fractional or decimal part. In mathematical terms, integers are the set of numbers that include all the natural numbers, their negatives, and zero.
03. Float
A float (short for "floating-point number") is a data type used to represent numbers that have a decimal point or are in scientific notation. Floats are used when you need to work with numbers that require more precision than integers, particularly for fractional values.
04. Array
An array is a data structure that stores a fixed-size sequence of elements, all of the same type, in a contiguous block of memory. Arrays are commonly used in programming to organize data so that elements can be accessed or modified efficiently using an index.
05. Variable
A variable is a symbolic name or container used in programming to store data that can be manipulated and referenced throughout a program. A variable holds a value, which can change (or vary) during the execution of the program. The value stored in a variable can be of different types, such as numbers, text, or more complex data structures, depending on the language and the needs of the program.
06. Syntax
Syntax in programming refers to the set of rules and conventions that dictate how code must be written for it to be understood and executed by the computer. Just as in natural language, where sentence structure and grammar must be followed to convey meaning, programming syntax defines the structure of statements, expressions, and commands in a programming language.
07. Function
A function is a block of reusable code that performs a specific task or set of tasks. It can take inputs (called parameters or arguments), perform operations on those inputs, and then return a result (or perform an action without returning anything). Functions help break down complex pr
08. Object
An object is a fundamental concept in object-oriented programming (OOP), which is a programming paradigm based on the idea of "objects" that contain both data and the operations (or methods) that can be performed on that data.
09. Operator
An operator in programming is a symbol or keyword used to perform specific operations on variables and values. Operators are the building blocks that allow you to manipulate data, perform calculations, or evaluate conditions within your code. In short, an operator performs an action on one, two, or more operands (values or variables) to produce a result.
10. Expression
An expression in programming is a combination of variables, values, operators, and functions that are evaluated to produce a result. An expression can be as simple as a single value, or it can be a more complex combination of operations. In essence, an expression is anything that results in a value.
