What are variables?


The word variables comes from the words "variable" and stands for variable values ​​in data processing technology.



Thus, this value is not a fixed number, but it can be changed, adjusted, or varied.

Variables are the opposite of constants, but take constant values ​​during the calculation (runtime).

A simple variable example:



Constants are: 1, 2, 3, 4, 123, 333, 44435, .... (constant values).
Variables are: x, y, z, value_1, value_2, value_3, value_4, ... (variable values).

Simple Variable Examples:



1.) The variable "X" has the constant value "3"

int X = 3;
X + 1 = 4;

2.) Variable "X" has the constant value "123"
int X = 123;
1 + X = 124;

3.) Variable "X" has the constant value "2" Y also "2"
int X = 2;
int Y = 2;
Y - X = 0 (NULL);

variabel = changeable = variable = mutable = erratic = adjustable = variably = adaptable
