Compare break and continue statement?
Break - will force to terminate the loop you are in to the nearest outer block.Continue - will force to skip the rest of the code in loop and take next iteration.Break for example is not only limited to loop constructions, it is also used in switch statement in order to stop executing following cases (works as described above, jumps out of switch).
When should a for loop be used instead of a while loop?
The golden rule in iteration: everything done with a for loop can be done with a while loop, BUT not all while loops can be implemented with a for loop. for-loops are just a short-cut way for writing a while loop, while an initialization statement, control statement (when to stop), and a iteration statement (what to do with the controlling factor after each iteration). = Examples of for-loops = The most basic use for using for-loops is to do something a set number of times: for(int k = 0; k < 10; k++); // this loops runs for 10 times another less common use of the for-loop is traversing raw listNodes, since it does contain an initialization(finding the first node), control (as long as there is a next node), and a iteration statement (get my next node). i.e.: for(ListNode temp = startingNode; temp != null; temp = temp.getNext); // this traverses the entire ListNode list and stops when it has exhausted the list = How to implement for-loops using while loop = Basically for loops are just short hand for while loops, any for loop can be converted from: for([initialize]; [control statement]; [iteration]); to [initialize]; while([control statement]) { //Do something [iteration]; } These two does the exact same thing. = For When Only while Loop can be used = while-loops are used when the exiting condition has nothing to do with the number of loops or a controll variable, maybe you just want to keep prompting the user for an input until the given input is valid, like the following example which demands a positive number: int x = [grab input]; while(x < 0) { // Do code x = [grab input]; } It is true that, when used as intended, a for loop cannot do everything a while loop can, however, in reality, for loops are just as versatile. For example, the above while loop can easily be rewritten to be a for loop as so: for(int x = [grab input]; x < 0; x = [grab input]){ // Do Code } The above for loop behaves exactly like the while loop in the previous heading. A better example of a while loop that should not be a for loop might be: while(true){ // Do some processing // Check some condition. If condition is met, break out of loop. // Do some more processing. } Here, the checking of the condition comes in the middle of the processing for the while loop, whereas the condition checked in a for loop is always done at the beginning of the loop. Also, the "iteration" statement is non-existant and is a factor of processing done somewhere else in the while loop. Finally, there was no initialization for this while loop. However, this while loop can still be written as a for loop: for(;true;){ // Do some processing // Check some condition. If condition is met, break out of loop. // Do some more processing. } As you can see, a for loop is exactly like a while loop if you leave out the initialization and iteration sections (you still needs the semicolons, to signify those parts of the for loop are still there, they just do nothing). However, it is clear that when you do not need the extra portions of the for loop, why not just use a while loop? The basic for loop was extended in Java 5 to make iterating over arrays and other collections more convenient.

What are the advantages of using a foreach loop over a for or while loop for processing list elements?
foreach can simply replace for loop. for ex in perl, if you need to copy display an array, it will take only foreach $var(@arr). then print $var. no need of incrementing the index of array like for loop.
What is the repetitive control structure in c plus plus?
C provides two sytles of flow control:BranchingLoopingBranching is deciding what actions to take and looping is deciding how many times to take a certain action. Branching: Branching is so called because the program chooses to follow one branch or another.if statementThis is the most simple form of the branching statements. It takes an expression in parenthesis and an statement or block of statements. if the expression is true then the statement or block of statements gets executed otherwise these statements are skipped.? : OperatorThe ? : operator is just like an if ... else statement except that because it is an operator you can use it within expressions. ? : is a ternary operator in that it takes three values, this is the only ternary operator C has.switch statement:The switch statement is much like a nested if .. else statement. Its mostly a matter of preference which you use, switch statement can be slightly more efficient and easier to read. Using break keyword:If a condition is met in switch case then execution continues on into the next case clause also if it is not explicitly specified that the execution should exit the switch statement. This is achieved by using break keyword. Try out given example Show ExampleWhat is default condition:If none of the listed conditions is met then default condition executed. Looping Loops provide a way to repeat commands and control how many times they are repeated. C provides a number of looping way. while loopThe most basic loop in C is the while loop.A while statement is like a repeating if statement. Like an If statement, if the test condition is true: the statements get executed. The difference is that after the statements have been executed, the test condition is checked again. If it is still true the statements get executed again.This cycle repeats until the test condition evaluates to false. for loopfor loop is similar to while, it's just written differently. for statements are often used to proccess lists such a range of numbers: do...while loopdo ... while is just like a while loop except that the test condition is checked at the end of the loop rather than the start. This has the effect that the content of the loop are always executed at least once. break and continue statements C provides two commands to control how we loop: break -- exit form loop or switch.continue -- skip 1 iteration of loop.
What is a reason for not using feedback control system?
The main reason for not using feedback control system is that time lag may cause a process deviation near the beginning of a process not to be recognized until the process output. It can result in substantial deviation throughout the entire process, causing an error to continue without adjustment. Since feedback control systems usually take input from one sensor. there may be better and more direct ways to control a system using multiple sensors. Operator intervention is usually required when the system is not able to maintain stable closed-loop control. Feedback control systems do not take predictive control actions for effects of known disturbances.
What is the use of continue in c?
Continue statement is used to take the control to the begining of the loop in which it is used.

The way the break is used to take control out of switch is same as continue to take control of the beginning of the switch?
yes

How does a WHILE loop work in GML?
The while loop works as follows:{while( [expression is true] ) {//Do this code}}The while loop re-runs until the expression contained within the parentheses is false. Take a look at this example:{while(!place_meeting(x,y,obj_ground)) {y += 1;}}This while loop tells the object to move down one pixel until it collides with obj_ground. Unfortunately, nothing guarantees that this loop will not run forever. Always make sure that when you construct a while loop that you make sure that it does not run forever. Take a look at this whileloop:{while(obj_ball.y < y) {draw_sprite(sprite_index,0,x,y);}} This while loop will run for ever. Why? It does not have any statements that insure that the while loop aborts. Again, Always make sure that when you construct a loop that you put statements in the loop that will eventually abort the loop. y -= 1; is the statement in this new while loop that eventually aborts the loop:{while(obj_ball.y < y) {draw_sprite(sprite_index,0,x,y); y -= 1;}}

What is an open loop system?
Open Loop control Systems have input, then the input is processed by various components like amplifiers, filters etc, then final out stage.The main difference between open loop and closed loop systems is that in open loop systems there is no feedback.

How to use for loop in vhdl code?
A loop statement is used to iterate through a set of sequential statements. The syntax of a loop statement is [ loop-label : ] iteration-scheme loop sequential-statements end loop [ loop-label ] ; There are three types of iteration schemes. The first is the for iteration scheme that has the form for identifier in range An example of this iteration scheme is FACTORIAL := 1; for NUMBER in 2 to N loop FACTORIAL := FACTORIAL * NUMBER; end loop; The body of the for loop is executed (N-1) times, with the loop identifier, NUMBER, being incremented by I at the end of each iteration. The object NUMBER is implicitly declared within the for loop to belong to the integer type whose values are in the range 2 to N. No explicit declaration for the loop identifier is, therefore, necessary. The loop identifier, also, cannot be assigned any value inside the for loop. If another variable with the same name exists outside the for loop, these two variables are treated separately and the variable used inside the for loop refers to the 34loop identifier. The range in a for loop can also be a range of an enumeration type such as type HEXA is ('0', '1', '2', '3', '4', ' 5', '6', '7', '8', '9', 'A', 'B', 'C', 'D', 'E', 'F'): . . . for NUM in HEXA'('9') downto HEXA'('0') loop -- NUM will take values in type HEXA from '9' through '0'. . . . end loop; for CHAR in HEXA loop -- CHAR will take all values in type HEXA from '0' through 'F'. . . . end loop; Notice that it is necessary to qualify the values being used for NUM [e.g., HEXA'('9')] since the literals '0' through '9' are overloaded, once being defined in type HEXA and the second time being defined in the predefined type CHARACTER
