What are the differences between a condition-controlled loop and a count-controlled loop?
A Condition-Controlled loop keeps going until a certain condition is met, like say the user clicks a button, or the world ends or something. A Counter controlled loop keeps going until it has run a certain number of times.
For example if you create a variable x=0. And then every time your look runs you increase x by 1 (x=x+1), you can tell your loop to keep running until x=5. That way the loop would run 5 times until the *COUNTER* reaches 5. This would be a counter controlled loop

When a VBScript loop control variable is not altered during loop execution what kind of loop may result?
An infinite loop.
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;}}
How does a FOR loop work in GML?
FOR loops work as follows:{for( [initialize a variable]; [expression]; [increment the variable] ) {//Do this code}}Here as an example of a FOR loop:{for(i = 1; i < 10; i += 1) {show_message(string(i));}}What this will do is show a message 10 times displaying the value of "i" so you would get a message that says "1," another one after that saying "2," etc... The way this works is that you have the variable "i" initialized in the FOR loop. The FOR loop will keep looping until i >= 10, because the middle statement dictates that i must be smaller than 10 for the FOR loop activate. The third statement in the for loop is the statement that you increment the i variable with. If you change i += 1 to i -= 1 then the FOR loop would go on forever, freezing the game. This is a critical mistake to make when constructing a FOR loop (as is with any loop.)
What is the purpose of wend statement in while loop in gw-basic?
While--wend statement is used to execute a loop until a given condition is true.if the condition is false the loop ends and the program continous to the line following eend.
What are the purpose of test condition in a loop statement in qbasic?
The purpose of using a 'test condition' inside of a loop statement/which is also called a 'conditional loop'; is to make the loop STOP counting. Otherwise, you would have gone and created what is known as being called an 'endless loop'; which just keeps on running really quite endlessly, forevermore...! To give a quick example, let's compare... CONDITIONAL LOOP EXAMPLE num% = 0 DO num% = num% + 1 PRINT num%; LOOP UNTIL num% = 3 END Output... 1 2 3 Press any key to continue... Here, when the LOOP's test condition is met: (num%=3); then, the loop stops counting up any further; the DO/LOOP block structure is broken out of; and, the final END statement will get executed. UNCONDITIONAL LOOP EXAMPLE Next, let's try re-writing the same above program; by removing the conditional statement part of the LOOP which says: (UNTIL num%=3)... num% = 0 DO num% = num% + 1 PRINT num% LOOP END Output... 1 2 3 4 5 6 7 8 9 10 11 12 .... ...because there is no conditional test statement to make the loop stop repeating itself; therefore, it just keeps on endlessly counting upwards, instead; the program never breaks out of the DO/LOOP block; and, therefore never gets to reach the final END statement. To make an 'unconditional loop' stop repeating itself inside of QBASIC IDE/Integrated Development Environment; then, use combination key press: [CTRL] + [BREAK]; and, this should make an 'endless loop' stop repeating itself any further; and, return you straight back to the Editor Screen where you can futher change/edit your code.
What are the differences between iterations and loops in progamming?
A loop will loop for n iterations. Each times the program executes the code in the loop is an iteration.
List out the differences between while and dowhile statement?
The do ..while loop is executed at least once, whereas the while loop may not be executed even once.
What are the differences between Do While and For loops in C?
In short, a for loop declares an variable and assigns it a value, has an argument, and has an update. A while loop only has an argument. More Detail... in C++, which is very close to C an example while loop is; while(i
Difference between while and do while loops in java?
The most important differences are: a. The while loop starts with a condition whereas the condition is the line of code in case of a do while loop b. The do while loop is guaranteed to run the loop body atleast once even if the condition is an impossible to satisfy but such a guarantee is not available with the normal while loop
What are the differences between while and do while?
while- It will wrok only if the condition is correct if not it wont excute the body of the loop do-while: In some cases we want that body of the loop and the condition may fails so the loop want to print so the do while loop first excute body of the loop and next it checks the condition it continues until the condition becomes false
What is the difference between heading ropes and heeling ropes?
The differences are the lengths of the ropes a head rope is 32ft and the heel rope is 35ft. Usually when your headin you want a smaller loop, with a heel rope you want a larger loop.
C program to print numbers 1 to n?
how do we use loops in c plus plus programing and what are basic differences between do,for and while loop
Differences between if else and while loop?
Easy: if-else is not a loop; while, for and do-while are loops.if-else just run once, but do-while run many times.
Tell 2 or 3 differences in table manner of differences between for and while loops?
Both For and While loops are available for the purpose of executing a piece of java code repeatedly until a particular condition is met. The only difference being - the loop condition/counter has to be modified inside the while loop every time whereas the condition is integrated in the for loop definition. Otherwise both the loops are exactly same in all aspects.
What do you call the flow in a air loop caused by differences temperature and pressure?
It is called a convection.
What are the 3 differences between for and while loop?
For Loop:1.In this first it initialized with the starting value such as I=0,count=0.The value which was initialized is then checked with the given test condition. While Loop:1.In this it checks the condition first. for Loop:2.In this we initializ,check conition and increment or dicrement in one statement While loop2:In this only we can test the condition in one statements. For Loop3:general Format: for (initialization; test condition; increment) { body of the loop } While loop:3.general Format while(test condition) { body of the loop }
Open loop and close loop system in injection moluld machine?
loop checking is perform before cable termination..the difference between a close loop and open loop is,tha close loop has a feedback while the open loop has not.
