Break and Continue Statements

The break statement in C is a powerful tool that alters the flow of control within loops. When encountered within a loop (like for, while, or do-while), break immediately terminates the loop’s execution, transferring control to the statement immediately following the loop.

How Break Works

Upon encountering the break statement, the loop exits, regardless of the loop’s conditional expression or any remaining iterations. This feature allows for efficient control of loops, enabling programmers to exit a loop prematurely based on specific conditions.

Implementing Break in C

In practice, break is frequently used within conditional statements to exit loops based on certain criteria. For instance, in a for loop iterating through a list of values, break can halt the loop if a particular condition is met, saving unnecessary iterations.

for (int i = 0; i < 10; i++) {
if (i == 5) {
break; // Exits the loop when i equals 5
// Perform operations here

Use Cases for Break

The break statement finds application in various scenarios. For instance, in search algorithms, once a target element is found, break halts the search, optimizing the algorithm’s performance.

Understanding Continue Statement in C

Similarly, the continue statement in C serves to alter the flow of control within loops but in a different manner compared to break.

How Continue Works

When encountered, continue skips the current iteration of the loop and continues with the next iteration, disregarding any subsequent statements within the loop for the current iteration.

Implementing Continue in C

Consider a for loop where specific conditions require skipping certain iterations:

for (int i = 0; i < 10; i++) {
if (i % 2 == 0) {
continue; // Skips even numbers, continues with the next iteration
// Perform operations on odd numbers here

Use Cases for Continue

The continue statement is beneficial when specific iterations need to be bypassed based on conditional logic, allowing for streamlined and optimized loop executions
