We have used loops in Ruby and we know that loops are very useful in Ruby because they often provide a convenient way to run the same piece of code, but what if we want to stop executing and exit in any instance? Loop, so in such situations we have a very useful feature in Ruby, which is a break, Brakes provide a way to stop running a loop at any time, for example, if you are searching for any data and once you get the data further search is useless, so with the help of break we can exit the loop once we get the required output. 

Below is the syntax of the break statement in Ruby, we can explain the syntax below for Ruby break in the following steps. 

In the first example, we are going to, we are using a while loop and expression, here expression is the condition, and on successful expression (true) the output code block will be executed.

We then have a comment section where we mention our arguments for conducting a search or an operation.

Once we get our required output from the code, running the code block over and over again is useless, so we have a code break that will get out of the loop. 

From the syntax, we understand that at any time if we see that we have received our output we can avoid editing for the next instructions.

 #We can consider  ,Iihasetookn an example of the while loop.
while expression
#write your code for searching your attribute from each value
# Use the break once you get the value for which you're doing this search.
break
end
end 
 

 How does the break statement work in Ruby :

With brake statements, we will be able to save unnecessary code execution and we will be able to save our expensive resources and processes. Let us understand the work of break-in Ruby with the help of the flowchart below. 

First, it will run the code block because it is a do-while loop. 

The next time the condition block comes to execute, each time it will check the conditions, in which case if the condition is successful again, it will execute the code block. 

One way to stop execution here is the failure of a condition block, another way to stop execution is to use a brake statement. 

In the figure below we can see that if the condition block fails or the play is interrupted, only the loop closes. 

We have taken the example of doing a while loop, but we can do the same with other loops. 

There are some important points about breaks because breaks will only work with the time and a loop. We may face some challenges while using it.

See the flowchart for break statements in Ruby.

An example of a break statement in Ruby  : 

The following is an example of a break in Ruby: 

Below is an example of where we are printing numbers. Here we are printing up to 5. We can explain the following code in the following steps. 

Here we are running a while loop which is checking the numbers, while the conditional statement will only check whether it is between 0 and 10. 

If the number exceeds 10, the loop will be closed. 

But our goal here is to print only up to 5, so breaks will play an important role here. 

So here we have used an if condition which is checking if the number that is going to be printed is more than 5, if the number is more than 5 then the statement will be broken and the loop will be closed. 

  #We are writing code where we are going to halt the execution of the code till 5
for number in 0..10
if number > 5 then
break
end
puts "The number is #{number}"
end 

Here in the example below we have taken arrays of some students and run a loop on them, the goal of our program is that once we find the "sujit" user we are going to run a commanding break which will stop the complete execution of the program. We can explain the code below in the following steps. 

First, we take an array of student variables. 

We are running a loop that can go to infinity because we did not use any specific condition, we just used the truth that will never change and the death penalty will continue. 

Finally, inside the code block we write a check with if condition, it will check if the student's name is "sujit", if it matches the break statement then it will be executed and the code execution will stop, which means the loop will be closed and left. Students will not be printed.

 student = ['ajay','ranjan','vijay','sujit','akash'] i=0
while true do
puts student[i] i += 1
break if student[i] == 'sujit'
end 
 

The goal of this code here is to add 3 to a number starting from 0 and we only want to print up to 9, the sum of which should be less than 12. Please follow the example below: 

 number = 0
while true
number += 3
puts "The sum of the two number is #{number}"
if  number + 3 >= 12
break
end
end 
 
 

From these tutorials, we have learned some important uses and basic concepts of break statements in Ruby with the help of some useful examples. We have also learned the function of a break with the help of a flowchart.

In Ruby, we use a break statement to execute a loop in the program. It is most often used in loops, where values ​​are printed ...
