Draw a Do-until loop

Answer 1

This is a loop function ... the loop will continue until something true happens. example: int i = 0; do { console.write(i + "< br />"); i++; }while(i < 100); This will loop 100 times.

Answer 2

A Do Until loop is a device used in programming. The loop runs until a certain criteria is met. An example might be a loop that keeps track of a set of scores until the total number of the scores reaches 4000.

Answer 3

A "do until" loop is a control structure that executes a block of code repeatedly until a certain Boolean conditional statement (e.g. end_of_file == TRUE) becomes true. Check with the specific language definition, but a "do until" loop just like a "repeat until" loop but unlike a "while" loop is likely to execute the code block at least once regardless of the initial value of the conditional.

An example of a do until loop is: do read word echo I just read $word until (word == EOF) An "each" loop executes a block of code once per list of things. An example is for each thing apples Pears cucumbers do echo I like to eat $thing done Both examples are just pseudocode, not any actual language.

Answer 4

Do Until tells the program to do something until smthing is true

for example lets say we have variable x which is equal to 5, if we do this

Do until x = 5

msgbox("x = 5")

end loop

the program will keep printing on msgbxs "x = 5" until x is actually not = to 5 (until x changes)

In for each (or for next) loop, the program checks if condition is true, if it is, it does something and loops doing that thing until the condition is false or vice versa

ex:

for each x = 5

do something

next

contnue code as normal

Answer 5

A Do-Loop, repeats a section of code until a certain condition has been met.

Count = 0

Do

Count = Count + 1

Msgbox(Count)

Loop Until Count = 5

This will make 5 message boxes appear, with the number 1 through 5 in them, they can cut down on the code you need to use.

Answer 6

In the C Programming language, the do-while loop is a loop construct whose body will be executed at least once, as the loop terminating condition is validated at the end of the loop's body.

Here is an example:

int main (int argc, char **argv) {

int i= 0;

do {

printf ("%d. '%s'\n", i, argv[i]); } while(++i

return 0;

}

Answer 7

In C and C++, a repeat until loop is created using a do-while loop structure. A do-while loop executes at least once and terminates when the while condition evaluates false, re-iterating the loop if the evaluation is true. This is in contrast to for and while loops which evaluate the condition at the start of each iteration, and may not execute at all.

Which loop structure you use is determined by the type of loop. If you need to count the iterations with a control variable and/or perform one or more actions at the end of each loop then a for loop is generally best. If the loop is simply conditional then a while loop is best. And if the loop must execute at least once, then a do-while loop is best.

Answer 8

Do while loop is a computer programming term that refers to a control flow statement and is often called a while loop or a pro-test loop. It allows a code to be executed once, based on a boolean condition. The code is executed and then the condition is evaluated. The code is always executed first and then evaluated. If the condition is found to be true, it continues to execute until it is found false. When its found to be false then it terminates and moves on to the next statement.
