3. What is true about a break? a) Pause stops the execution of the entire program b) Pause stops execution and forces control out of the loop c) Pause forces control out of the loop and begins the execution of the next iteration d) Pause stops running the loop for a while Show response The name of the collection variable in the enhanced FOR loop must be preceded by a colon. 9. Where does the declaration of termination cause an exit? a) Only from the innermost loop b) Terminates a program c) Only from the innermost switch d) From innermost loops or switches Show response Which of the following are legal loop constructs? (Select all that apply.) The WHILE loop and the DO-WHILE loop operate at the same speed. A Do-While loop executes the statements it contains, even if the condition is false. For this reason, a DO-WHILE loop is used in MENU-driven console Java programs. Do-WHILE prints for the first time (1,2,3). In the next iteration of i=2, the value of j is already 4. It is therefore printed and checked for condition (j<4). The inner loop ends. In the third iteration with i=3, nothing is printed. CONTINUE brings program execution to the beginning of the loop by ignoring the current iteration. In B, the loop control expression – in this case, the variable i – is of type int.

D is wrong, the label was omitted in the 2nd line, which should be Before the PRINT instruction is reached, the outer loop stops because of BREAK outer. Use labels only to select external loops. Otherwise, simply use PAUSE or CONTINUE without labeling. Only the DO WHILE loop executes the statements at least once. When writing a DO-WHILE loop, there must be a semicolon at the end of the while(condition) part. The condition part is not necessary because the extended FOR loop runs through all items in the collection from wait to finish. Response B has a WHILE loop that immediately ends with a semicolon. It is therefore a false statement. Also solve Python if-else, for the loop and range() exercise. This type of declaration is only allowed in the first part of a for() loop.

4. What is true in this statement? a) the do statement executes the code of a loop at least once b) the do statement is not executed if the condition does not match the first iteration c) the do statement checks the condition at the beginning of the loop d) the do statement always executes the code more than once The Show response BREAK condition is checked after the «score» variable is printed. So it also prints 4. Note that there is no semicolon at the end of the INCREMENT/CREMENT part. The CONTINUE statement ignores the execution of the remaining statements below. The semicolon after WHILE (condition) is missing. 2. Given the if-else nesting below, what will be the x value if the successfully executed code fails the WHILE condition. At this point, the incremental statement was executed once. Its new value is therefore 21.6. What is the valid data type for variable «a» to print «Hello World»? The keyword «goto» is always a reserved keyword. It cannot be used.

The semicolon after the INCREMENT/CREMENT part is not allowed.
