Question
1.Fill it with buttons, each containing a description indicating which question it will answer.
Each button will answer only one of the questions (3A, 3B, 3C, 4A, 4B, 4C and 4D).
2.When the button is clicked a function is called one for each loop below and record your responses as a JS comment inside each of those functions you have just defined.
A.How many times does the following loop execute and why is the output not displayed on a single line?
for (var a = 0; a < 5; a++)
{
document. write (“Go Gamecocks!!<br>”);
}
B.What is written to the document by the following loop?
var k = 12;
while (k >= 7)
{
document. write (k + "th item, “);
k = k - 1;
}
C.Explain how the following code works in your comment after defining a function that performs this task.
do
{
var userInput = prompt (“enter password:”, “type password here”);
}
while (userInput != “aAbBcC”)
3.Write the JavaScript code for the following tasks. Each number in the output generated must be printed on a new line.
A.A for loop that loops 7 times and prints out: 0 1 2 3 4 5 6.
B.A while loop that loops 6 times and prints out: 2 4 6 8 10 12.
Hint: you can increment your iterator by more than just 1.
C.A do while loop that loops 5 times and prints out: 1 2 3 4 5.
D.A for loop that loops 7 times and prints out: 1 8 27 64 125 216 343.
Hint: use the Math.pow(x,3) method in the body of the loop.
