Loops Practice Exercises

Part A $($for$-$loops$)$

Write six for$-$loops that produce the following series of numbers. Your loops should print each series on the same line, with one or more spaces between each number as shown below.$$ If you want to include the number at the start of each of these, use another variable.$$ Then increment it $($add one to it$)$ and print it before your for loop code.

$45678910$

$654321$

$246810121416$

$1917151311975$

Part B $($while$-$loops$)$

Write a collection of while$-$loops that solve the following problems. The steps for the first problem have been given to you:

$1.$ Prompt the user to enter a positive integer n$.$ Print out all positive integers from $1$ to n$.$

For example:$12345...$ n

Use the following steps to solve this problem:

Prompt the user to enter a positive integer, then store the result in an integer variable named $$n$$

Hint: Use a form that has no action or the action is loops.php $($this form posts to loops.php$).$ Add code to loops.php to check whether that the form element isset or exists.$$ Use an if condition to decide whether to execute the while loop.$$ Nest the while loop within an if block.

Declare an int variable called $$count$$Write a while loop that uses your $$count$$ variable to loop from $1$ to n $($what should your condition be$?)$Print out $$count$$ in your loop

$2.$ Write a while loop that calculates and prints the sum of the first $10$ positive integers.

For example, calculating the following sum:

$1+2+3+4+5+6+7+8+9+10,$

would print $55.$

$$

Part C $($nested loops$)$

$1.$ Write a collection of nested loops that solve the following problems.

$$Display the following table of numbers in your web browser.

$123456789$

$123456789$

$123456789$

$2.$ Draw the following rectangle on the console $($web browser$).$
