Variable
symbols that represent unspecified numbers or values.
In computer programming and mathematics, a variable is a symbolic name assigned to a value or data storage location that can change its value during program execution or be different in different circumstances. It is a container that holds a value, which can be manipulated, modified, or accessed by a program.
Variables are crucial in programming because they enable storing and organizing data, performing calculations and logical operations, and controlling the flow of a program’s execution. They can be of different data types such as integer, floating-point, Boolean, string, and others, depending on the stored value.
A variable has a name, a data type, a value or storage location, and a scope that determines the part of the program where it can be used. The value of a variable can be assigned at the point of its declaration or later in the program by using operators or functions to change its value. A variable can also be used as an argument to a function or passed as a parameter to another function.
In brief, a variable is a fundamental concept in programming and math, which allows creating dynamic, flexible programs that can adapt to various situations, process data, and generate results.
