Break statement in C++ is a loop control statement defined using the break keyword. It is used to prevent the present-day execution and proceed with the subsequent one. Whilst a compiler calls the ruin statement, it immediately stops the execution of the loop and transfers the control outside the loop, and executes the opposite statements. Within the case of a nested loop, breaking the assertion stops the execution of the inner loop and proceeds with the outer loop. The announcement itself says it breaks the loop. When the break declaration is referred to as within the software, it right now terminates the loop and transfers the waft manipulate to the declaration cited outdoor the loop. In this article, we're going to see the idea of the break.

The break statement is used in the following scenario:

When a user is not sure about the number of iterations in the program

When a user wants to stop the program based on some condition.

break Keyword is used to represent the break statement.

How does Break Statement work in C++ Language?

The break statement terminates the loop where it is defined and carried out by the other. If the condition is noted within the program, primarily based on the circumstance, it executes the loop. In the flowchart diagram, you can see that the primary checks the circumstance. If the condition is real, it executes the conditional statement, and if the ruin statement is referred to, it's going to right now break the program. Otherwise, the loop will iterate until the given circumstance fails. If the condition is false, it stops this system.

To understand the concept of the break statement in c++, we will see some examples.

Example #1 – Use of Break Statement in for loop

The program for using Break statement in for loop is given as follows:

Here we have used a break statement in for loop. We have written a program to print numbers from 0 to 10. First, we initialize the I variable in for loop; we have to initialize the I variable to 0 to start the loop at 0 to print until 10; we have mentioned the condition less than equal to 10. And to increment the number, we have used increment. Inside for loop, the cout is used to print the value of i. To break the loop at 8, we have used the if statement to check if the number is equal to 8 breaks the loop and transfer the control outside the loop.

Example #2 – Use of Break Statement in while loop

Program for using Break statement in while loop is given as follows.

Here we have used break statements in a while loop. Here we have written a program to print the value of 1 by multiplying it by 2. First, we have initialized 1 to 10 and mentioned a condition using a while loop to check if the number is less than or equal to 100. If the condition is true, it will print the value of i. The break statement is mentioned to break a value at 80. Up to 80, the loop will iterate by executing the statement. When the break statement condition match, the program will break.

Example #3 – Use of Break Statement in switch Case

The program for using Break statement in Switch Case is given as follows:

case 1: cout <<"You have entered 1" << endl;

case 2: cout <<"You have entered 2" << endl;

case 3: cout <<"You have entered 3" << endl;

case 4: cout <<"You have entered 4" << endl;

case 5: cout <<"You have entered 5" << endl;

default: cout << "Please enter valid value";

Here we have used a break statement for the switch statement. A switch statement is used to check the case and print the value. Here we have written a program to allow a user to enter a value between 1 to 5. A switch statement is used to check the condition. If the user enters a number from 1 to 5, it will execute the corresponding case. If the user enters a value except 1 to 5,  it will execute the default condition. The break statement is used in Every case statement to break the statement.

Today we will discuss Break Statement in C++

Break Statement in C++

Break Statement in C is a loop control proclamation that is utilized to end the loop. There are two utilizations and the given assertion is clarified underneath.

Inside a Loop: If the break statement is utilized inside a loop alongside the if statement then, at that point, if the condition turns out to be valid the loop is quickly ended and the following statement after the loop begins executing by the program control.

Inside a Switch Case: If Break Statement in C is utilized inside a switch case after each switch case then the break statement ends a case after executing the case.

Overall the break statements we utilized in the circumstances where we want to stop the loop execution in light of the condition or not certain how frequently the loop is to be repeated. If the break statements utilizing inside the settled loop, then, at that point, the break statement breaks the inward loop and starts executing the statement after the internal loop of the program control proceed to the external loop.

Examples to Implement Break Statement in C:

printf("The loop terminat at co = %d", co);

printf("Enter the option \“A\”, \“B\”, \“C\” or \“D\” :");

printf ( "You have not entered option A, B, C, or D, wrong input ");

Break statement inside the nested loop, in nested case, it breaks only the inner loop, but not outer loop, as can be understood by the code.

printf("outer = %d & inner = %d loop running\n",outer,inner);

So as in the above output, when outer = 3 & inner = 2 the inner loop break, and the execution continue to the outer loop for the 4th iteration.

Consider the following example to use the break statement inside the while loop.

During this blog post, we will gain a deeper understanding of break statements in C, we will learn about their flowcharts, as well as examples.
