## break

The `break` keyword is a loop terminator, allowing you to exit a loop prematurely.

Example 1: Stopping an Infinite Loop

In this example, the `break` keyword stops the infinite `while` loop when `i` becomes equal to `6`, after the `i++` operation.

Example 2: Breaking a `for` Loop

Here, the variable `a` is incremented by `i` during each iteration (0 + 1 + 2 + 3 + 4) until `i` becomes equal to 4. At that point, the `break` statement is triggered.

 `i = 0` `a = 0 + 0` `i = 1` `a = 0 + 1` `i = 2` `a = 1 + 2` `i = 3` `a = 3 + 3` `i = 4` `a = 6 + 4`, `break`

Example 3: Breaking a `while` Loop Immediately

In this example, the `break` statement inside the `while` loop immediately terminates the loop, preventing any code below it from executing within the same block.

Note

Remember that the `break` statement is a powerful tool for controlling the flow of your loops, allowing you to exit them when specific conditions are met.
