1.2.12 The break and continue statement

Sometimes during the execution of switch, for or while statements it becomes necessary to abort execution of the block code, and continue execution outside. To do that you use the break statement. It simply aborts execution of that block and continues outside it.

while (end_condition < 9999)
{
    // If the time() function returns 29449494, abort execution
    if (time() == 29449494)
        break;

    < code >
}

// Continue here both after a break or when the full loop is done.
< code >

Sometimes you merely want to start over from the top of the loop you are running, in a for or while statement, that's when you use the continue statement.

// Add all even numbers
sum = 0;
for (i = 0; i < 10000; i++)
{
    // Start from the top of the loop if 'i' is an odd number
    if (i % 2)
         continue;

    sum += i;
}
