C++ break and continue statements
In C++, break and continue are branching statements used within loops to control the flow of execution. They serve different purposes:
C++ break statements
break is used to exit the current loop prematurely when a certain condition is met. It allows you to terminate the loop immediately and continue with the code following the loop.
In this example, the loop will print numbers from 1 to 4 and then exit when i becomes 5 due to the break statement.
break with Infinite Loops
break is often used within infinite loops to provide a mechanism for manually terminating the loop when a specific condition is met. Without break, an infinite loop would execute indefinitely, consuming resources and potentially freezing the program.
By including a conditional statement with break within an infinite loop, you can control when and under what circumstances the loop should terminate, allowing your program to remain responsive and efficient.
In this example, the loop runs indefinitely (while (true)) but terminates when the specified condition (condition_met) is met, thanks to the break statement. This usage of break is crucial for creating responsive and controlled loops in situations where the number of iterations isn't known in advance.
C++ continue statements
continue is used to skip the rest of the current iteration of a loop and move to the next iteration, based on a certain condition. It allows you to effectively bypass the remaining code within the current loop iteration and proceed with the next iteration.
In this example, the loop will print numbers 1, 2, 4, and 5, skipping the iteration where i is 3 due to the continue statement.
break is a branching statement used to exit the current loop prematurely when a specified condition is met, allowing for the termination of the loop. continue is a branching statement that skips the rest of the current iteration within a loop and proceeds with the next iteration, based on a specific condition, facilitating the bypass of specific loop iterations. Both statements are vital for controlling the flow and behavior of loops in C++ to meet specific programming requirements.
