In addition to loops, conditionals, and iterators, Ruby has some statements that are used to change the control flow in a program. In other words, these statements are pieces of code that execute one after the other until a condition is met.In this article, we will explore the following control flow alterations in Ruby −break statementnext statementredo statementretry statementLet's consider each of these one by one.break statementWhen a condition is True in Ruby, the break statement terminates a loop.ExampleConsider the code shown below.# break statement example itr = 1 while true if itr * 6 >= 35 ...

break Statement in RubyIn Ruby, we use the break statement in order to make sure that we exit a certain loop after a condition. For example, suppose we want to print the numbers from 1 to 10, but once we hit the number 5, we just don't want the loop to print any numbers that come after it. In such a case, we can use the break statement.Example 1Let's take an example and understand how the break statement works in Ruby. Consider the code shown below.# break statement in Ruby #!/usr/bin/ruby -w itr = 1 # while Loop ... Read More
Sometimes we may want to exact a portion from an array data and perform some operation on it. In Ruby, we can do that with the help of the slice() function that takes two arguments, both of them indices, that are used to define a subsequence which then can be extracted from the array.SyntaxThe syntax of the slice() function is shown below −res = Array.slice(x, y)Here, x and y denote the starting index and the ending index, respectively.Example 1Now that we know a little about the slice() function on arrays, let's take a couple of examples and see how to ...

Sometimes we need to extract a portion of an array data and perform some operation on the extracted data. In Ruby, we can perform such operations with the help of the shift() function.The shift() function takes one argument, which is an index that is used to remove the first element from that index and return all the elements before it. If the index is somehow invalid, then it returns nil.SyntaxThe syntax of the shift() function is shown below −res = Array.shift(x)Here, the argument "x" denotes the starting index.Example 1Now that we know a little about the shift() function on arrays, ...
