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). Small 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 = adaptableFAQ 6: Updated on: May 25th 2018 21:31 |
