The goto statement is used to alter the normal sequence of the program execution by transferring control to some other part of the program. In its general form, the goto statement is written as: goto label; Where label is an identifier that is used to label the target statement to which control will be transferred. Control may be transferred to any other statement within the program. The target statement must be labeled, and the label must be followed by a colon. Thus, the target statement will appear as: label: statement Each labeled statement within the program must have a unique label; i.e., no two statements can have the same label.
Breaking Control Statements in C++
The continue statement is used to bypass the remainder of the current pass through a loop. The loop does not terminate when a continue statement is encountered. Rather, the remaining loop statements are skipped and the computation proceeds directly to the next pass through the loop. The continue statement can be included within a for, a while or a do-while statement. The continue statement is written simply as: continue; without any embedded expressions or statements. The continue is a keyword in the C++ program and the semicolon must be inserted after the continue statement.
The break statement is used to terminate loops or to exit from a switch. It can be used within a for, a >code>while, a do-while or a switch statement. The break statement is written simply as: break; without any embedded expressions or statements. The break is a keyword in the C++ program and the semicolon must be inserted after the break statement. We have already seen the use of break statement within the example of switch statement (Click here). The break statement causes a transfer of control out of the entire switch statement, to the first statement following the switch statement.
