constant means a value that never changes for example if you create a constant variable a and assign it with 10..... then you can't change value of a..... but if you create a simple variable a and assign it with 10..... you are free to change it's value any time in the program. 😊

Constant = Always its value is fixed. Variable = Its value changes when condition / conditions is / are changed.

constant which does not change their state and value e.g=1,2,3 where 1 is constant it can not change his value like 1=2 it's wrong. variable which can change their value means they contain some value like y=2 and y can change his value like y=6,y=8 and so on.

Constant ="Values that do not change" eg. 10,1.5,"a" Variable =."sort of a container to contain constants" eg. x=10

variables value can be changed anywhere u want in the program.. but constant once declared and initialized will have the same value even if u try to change it anywhere in the program..

@dAisy, time itself is a variable.

constant variable has its fix value and that is initialized at the time of declaration , later we can not change that value. If we do so that will cause an error. Variables value can be changed any where in program.
