Iterative statements are termed as loops; as with any other programming language, loops also exist in Ruby programming. Let's use them and see how their syntax differs from other languages:
def forl(a)
for i in 0..a
print("Number #{i}n")
end
end
forl(10)
The preceding code iterates the loop from 0 to 10, as defined in the range, and consequently prints out the values. Here, we have used #{i} to print the value of the i variable in the print statement. The n keyword specifies a new line. Therefore, every time a variable is printed, it will occupy a new line.
Iterating loops through each loop is also a common practice and is widely used in Metasploit modules. Let's see an example:
def each_example(a) a.each do |i| print i.to_s ...
