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
How do you print the first 20 even numbers in qbasic?
startNum% = 0 endNum% = 38 counter% = 1 PRINT "Counter", "Number" PRINT FOR num% = startNum% TO endNum% STEP 2 PRINT counter%, num% counter% = counter% + 1 NEXT *NOTE*: This prints out all of the even numbers starting from 0 up to 38; if you didn't wish 0 to be included as well; then, change it to say... startNum% = 2 endNum%= 40
A negaotive times a positive equals?
a negative but of there are a equal number of negatives then a positive... the negatives counter each other
What is a counter example for the statement that all odd numbers are prime?
9 = 3 x 3 15 = 3 x 5 etc. Any odd number that is composite. But 2 is a prime number which is not an odd number. [Wrong question: that is a counter example to all primes are odd numbers]
What number would be a counter example to the following conjecture. Prime numbers are odd?
The number 2 is even as well as prime.
What three actions do count loops typically perform using the counter variable?
Test initialize increment
What are the three actions a loop performs using a counter variable?
for (initialisation; condition; update) { /* ... */}
Print 1-10 numbers using while loop?
public static void main(String args){ int counter = 0; //initialize the counter variable to 0 while (counter < 10){ //while the counter variable is less than 10... counter ++; //increase the counter variable by 1 System.out.println(counter); //print the counter variable } }
A loop control variable that is incremented a specific number of times is known as?
A loop control variable is widly known as a "counter".
What is the correct way to add 1 to the count variable?
A counter variable is "incremented" (the step number, 1 in this case, is added to it) in any of the following four ways: $counter = $counter + 1;$counter += 1; //this is shorthand for the above $counter++; //postfix increment operator $counter = 0;echo $counter++;The output would be 0++$counter; //prefix increment operator $counter = 0; echo ++$counter;The output is 1
Can you display the contents of the counter variable in the body of a loop?
Yes.
What are the three actons a counter variable uses?
Variables don't have any "actions". A variable provides storage for a value, nothing more. A counter variable is typically used in a bounded for loop. A for loop has three clauses, each of which is optional. The first clause is the initialiser which can be used to initialise a control variable upon entry to a bounded loop. The second clause is the conditional expression which is evaluated at the start of each iteration. If that expression evaluates false, execution passes to the statement following the for statement, otherwise the body of the loop executes. The second clause is typically used to test the control variable is within the bounds of a bounded loop. The third clause is an operation that will be performed at the end of each iteration. In a bounded loop, this clause is typically used to increment the control variable. For example: for (int x=0; x<10; ++x) { /* ... */ } The above loop is a bounded loop that will execute the body of the loop 10 times. The control variable, x is first initialised to 0. At the start of each iteration, if x<10 is true, the body of the loop will execute one iteration. At the end of each iteration, the ++x statement increments x. When x is 10, the x<10 expression becomes false and execution passes to the statement immediately after the for loop.
How do you display 1 to 100 using loops in c?
To display 1 to 100 using loops in C, you must first declare a variable. This variable will be the one to be printed it's increasing values. The variable must increment by 1 every time the loop loops. While the loop counter does not exceed 100, the loop will continue. Example code: int counter = 0; int value = 0; for (counter = 0; counter <= 100; counter++) { value++; // (increment) increase value of variable "value" by 1 printf("%d\n", value); }
Which loop is specifically designed to initiate test and increment a counter variable?
for loop
What is an antiprogram?
An antiprogram is a set of actions used to counter those of another's program.
How long does cake last on the counter?
A cake will typically not last very long if left on the counter. This is because people will eat it.
