===Using break to Exit a Loop===

It is possible to force an immediate exit from a loop, bypassing any code remaining in the body of the loop and the loop’s conditional test, by using break statement. When a break statement is encountered inside a loop, the loop is terminated, and program control resumes at the next statement following the loop. Here is an example:

{| class="tableintopic" style="border-collapse: collapse" width="590" cellpadding="2" bgcolor="#C0C0C0"
|- align="left" valign="top"
| width="590" bgcolor="#C0C0C0" |
{

number i = 1;

while (i&lt;10)

{

if (i==6) break;

print(i);

i = i + 1;

}

print("Counting completed.");

}

The output from the script is shown here:

{| class="tableintopic" style="border-collapse: collapse" width="590" cellpadding="2" bgcolor="#C0C0C0"
|- align="left" valign="top"
| width="590" bgcolor="#C0C0C0" |
1

2

3

4

5

Counting completed.

In nested loops, the break statement in the inner loop causes only the termination of that loop. The outer loop is unaffected.
