Simple Constructs in Ruby

Today, we shall explore some very simple constructs available in Ruby. The example below (Constructs.rb) illustrates the if else end construct.

# if else end
var = 5
if var > 4
  puts "Variable is greater than 4"
  puts "I can have multiple statements here"
  if var == 5
      puts "Nested if else possible"
  else
      puts "Too cool"
  end
else
    puts "Variable is not greater than 5"
    puts "I can have multiple statements here"
end

An example of using elsif is there in the program ElsIfEx.rb

Some common conditional operators are: ==, != >=, <=, >, <

Loops like the while are available. Again, the example below illustrates the same.

# Loops
var = 0
while var < 10
    puts var.to_s
  var += 1
end

I shall talk about another construct the do end when we discuss arrays.
