1. The break and continue Statements
• break
– Causes immediate exit from a while, for, do/while or
switch structure
– Program execution continues with the first statement after the
structure
– Common uses of the break statement
• Escape early from a loop
• Skip the remainder of a switch structure

2. The break and continue Statements (II)
• continue
– Skips the remaining statements in the body of a while, for or
do/while structure
• Proceeds with the next iteration of the loop
– while and do/while
• Loop-continuation test is evaluated immediately after the
continue statement is executed
– for structure
• Increment expression is executed, then the loop-continuation test
is evaluated
