  • In the equation y = mx + b, both x and y are variables.
  • You need to declare variables before using them in a program.
placeholders

Used in various contexts such as templates, forms, and programming to temporarily hold a place for a variable or value that will be specified later. Can also be found in printed documents and graphical design.

  • In a template, {name} is a placeholder that will be replaced with the actual name.
  • Use underscores as placeholders until you find the actual data.
identifiers

Used primarily in programming to name elements such as variables, functions, classes, etc. Must follow specific naming conventions in different programming languages.

  • The identifier 'myVar' is used to store the value.
  • Good identifiers are descriptive and make code easier to understand.
symbols

Can refer to a variety of representations including special characters in mathematics, notation in programming, and icons in graphical interfaces. Often used to represent operations, functions, or other specific meanings.

  • In mathematics, ฯ€ is a symbol representing the number pi.
  • In some programming languages, the $ symbol is used to denote variables.

Etymology

The term 'variable' originated from the Latin word 'variabilis', which means 'changeable'. In the context of computer programming, the concept of variables was introduced to allow for the dynamic manipulation of data within a program. Over time, variables have become a fundamental concept in programming languages, enabling developers to write more flexible and powerful code.

See also: invariable, variableness, variably.
