Promenljiva

Promenljiva, also spelled promenljiva, is a term used in the context of computer programming and mathematics to refer to a variable. A variable is a storage location identified by a memory address and a symbolic name, which contains some known or unknown quantity of information referred to as a value. Variables are fundamental to programming as they allow for the storage and manipulation of data.

In programming, variables are used to store data that can be changed during the execution of a program. They are declared with a specific data type, which determines the kind of data that can be stored in the variable. Common data types include integers, floating-point numbers, characters, and strings. For example, in the programming language Python, a variable can be declared and assigned a value as follows:

x = 10

In this example, x is a variable of type integer with the value 10. The value of x can be changed throughout the program, hence the term "variable."

In mathematics, variables are used to represent unknown quantities in equations and expressions. They are typically represented by letters, such as x, y, or z. For example, in the equation 2x + 3 = 7, x is a variable representing the unknown quantity that satisfies the equation.

In summary, promenljiva is a versatile concept used in both programming and mathematics to represent values that can change or be unknown. It plays a crucial role in enabling dynamic data manipulation and solving mathematical problems.
