How decalring variable in Ruby Programming Language

http://www.mediawiki.org/wiki/User_talk:Paopao86

Working with variables

You can manipulate variables in exactly the same way that you would manipulate the objects that they represent.

The good thing about variables is that you can keep track of information more easily. Suppose that you were given these instructions:

  1. Add 2, 4 , 6 and 8 together.
  2. Take that result, and divide it by 5
  3. Take the product of 2, 3 and 4.
  4. Take your answer from line 2 and subtract it from what you got in line 3.

Sure, you could write out a long expression to do this. It is much easier to write:

Shortcuts

In the example above, you saw the expressions:

num1 = num1 / 5
num2 = num2 - num1

These kinds of expressions are very common, so Ruby offers you some shortcuts:

Example ShortcutMeaning
var = var + 2var += 2 Add 2 to var
var = var - 3var -= 3 Subtract 3 from var
var = var * 6var *= 6 Multiply var by 6
var = var / 2var /= 2 Divide var by 2
var = var** 3var **=3 Cube var
var = var % 4var %= 4 var modulo 4

So the above example could be written as

Constants vs. Variables

Constants are like variables, except that you are tellig Ruby that their value is supposed to remain fixed. If you try to change the value of a constant, Ruby will give you a warning.

You define constants just like variables, except that the first letter is uppercase.

Note: Though City is a "constant", its value still changed. Being a constant only means that Ruby will warn you if you change its value. See below.
