Calculate coins
Chapter 7 Screen Capture.JPG

• This application allows the user to enter a number of cents from 0 to 99.
• When the calculate button is clicked, this application displays the fewest number of coins for each denomination needed to add up to the amount of cents entered by the viewer
Create the application describe below. Be sure to follow all of the instructions provided.
Temperature Converter
User interface

Operation
• This application allows the user to select the type of temperature conversion.
• If the user selects one of the radio buttons, this application disables the text box that’s used to display the results of the calculation, it enables the text box that’s used to get data from the user, and it removes any data from both text boxes.
• This application displays the converted temperature in the disabled text box when the user clicks on the Convert button.
Specifications
• The formula for converting temperatures from Fahrenheit to Celsius is:
c = (f-32) * 5/9
• The formula for converting temperatures from Celsius to Fahrenheit is:
f = c * 9/5 + 32
• This application should accept decimal entries like 77.5, but it should round the result of the conversion to the nearest integer value.
• This application should validate data to make sure that the user enters a valid number for the conversion.
Note
• To disable or enable a text box, you can set its disabled property to true or false.
Student Scores
User interface

Operation
• This application stores the last name, first name, and score for one or more students and it calculates the average score for all of the scores that have been entered.
• When the user clicks on the Clear button, this application clears the score data from this application.
• When the user clicks on the Sort button, this application sorts the data in alphabetical order by last name. NOTE: the sort method does not work in Google Chrome as described in your text. For this reason I used Firefox for grading purposes.
Specifications
• The program should use one or more arrays to store the data.
• Assume that the user will enter valid data
