what is a variable in computer science In computer programming a variable is an abstract storage location paired with an associated symbolic name which contains some known or unknown quantity of data or object referred to as a value or in simpler terms a variable is a named container for a particular set of bits or type of data like integer float string etc 1
A variable is a named unit of data that is assigned a value If the value is modified the name does not change Variables are used with most programming languages and come in many forms defined by the script or software programmer Some variables are mutable meaning their values can change Variable can be thought of as a box that the computer can use to store a value The value held in that box can change or vary program can use as many variables as it needs it to All

What is a variable In programming a variable is a value that can change depending on conditions or on information passed to the program Typically a program consists of instruction s that tell the computer what to do and data that the program uses when it The official definition in computer programming a variable is a storage location paired with an associated symbolic name an identifier which contains a value In other words a variable is a storage location for data Variables have names Some computer language mandate you assign a data type to variables When asked for the
At the most fundamental level a variable can be seen as a storage box in the memory of a computer This box can hold different types of values which can be retrieved or changed as needed The computer uses the variable s name as an address to access its content The variable is a like a box or container that holds the thing that is changing The box stays the same but whatever is inside can change or vary The computer can store

Variables A variable is a named piece of memory that holds a value The value held in a variable can and usually does change as the program is running A variable s name A variable is a connection between a name and a value That sounds simple enough but some complexities arise in practice To avoid confusion later we ll spend some time now looking at the idea of variable in more detail The name variable comes from algebra Many people are introduced to variables in high school algebra classes where the
