Task 1
A. Define and describe the steps to program development.
B. What is an Algorithm? Discuss and provide examples (using psuedocode).
C. How do you put JavaScript into a web page? Explain.
Task 2
A program is required to read in the maximum and minimum temperatures on a particular day and calculate and print the average temperature. Develop the psuedocode to perform this task. Desk Check your solution.
Task 3
A program is required by a company to read an employee's number, pay rate and the number of hours worked in a week. The program is then to compute the employee's weekly pay and print it along with the input data. According to the company's rules, no employee may be paid for more than 60 hours per week and the maximum hourly rate is $25.00 per hour. If more than 35 hours are worked then payment for the overtime hours worked is calculated at time a half. If the hours worked field or the hourly rate field is out of range, then the input data and an appropriate message is to be printed and the employee's pay is not to be calculated
Task 4
A temperature file consists of fifteen records, each containing a temperature in degrees Fahrenheit. A program is to be written which will read and print both temperatures in two columns on a report. Column headings, which read ‘Degrees F' and ‘Degrees C', are to be
printed at the top of the page.
Task 5
Develop JavaScript code that prints current date in the top right corner of your Web page
Task 6

J.
Refresh this page in 3 seconds...
Task 7
Create a JavaScript clock using functions where appropriate.
Task 8
Create a Multiplication Table Using Nested Loops.
Task 9
Given the following code:
var n = prompt("Check your number", "Type your number here");
n = parseInt(n);
if (isNaN(n))
{
alert("The input cannot be parsed to a number");
}
else
{
if (n == 0)
{
alert("The number is zero");
}
else if (n%2)
{
alert("The number is odd");
}
else
{
alert("The number is even");
}
}
Answer the following questions:
1. With which object would you associate the prompt() method?
2. Prompt() takes two arguments. Where are they displayed?
3. The input from a prompt() is of which data type?
4. What is the function of parseFloat() and parseInt()?
5. What will be result if we send "abcd" through a prompt() input and pass it through parseInt()?
6. What is the use of isNaN()?
