Program Plan Intro

Modified Diamond-Printing Program

Program Plan:

Filename: “Diamond.java”

  • Import the header file.
  • Define the “Diamond” class
    • Define the “drawDiamond” method
      • Create an object for “Scanner” class
      • Declare the required variables
      • The “do-while” loop is used to get the number of rows from the user.
      • Iterate “row” value from 1 to “numRows/2” for displaying top triangle
        • Iterate “spaces” value from “numRows/2” to “row” value
          • Display empty space
        • Iterate “stars” value 1 to “(2 * row) - 1” value
          • Display the “*” symbol.
        • Display the newline.
      • Iterate “row” value until it reaches the value greater than or equal to 1 for displaying bottom triangle
        • Iterate “spaces” value from “numRows/2” to “row” value
          • Display empty space
        • Iterate “stars” value 1 to “(2 * row) - 1” value
          • Display the “*” symbol.
        • Display the newline.

Filename: “Test.java”

  • Define the “Test” class
    • Define the “main” method
      • Create an object for “Diamond” class
      • Call the “drawDiamond” method

("View all employees" function) If users click "View all employees" ( call program:view_employee.php), your program should(i) Retrieve all employees from TECH3740. EMPLOYEE table and list all employees in HTMLTABLE format(ii) If the salary is NULL, print it in red color.(iii) If Gender='M', print it in blue color. If Gender='F', print it in red color.(iv) Display the average salary of listed employees at the bottom of the employee table.(v) A statement "There are # employee(s) in the database." should be displayed above theemployee table, where # is the number of employees.
C# (Guess the Number Game) Write a program that plays “guess the number” as follows: Your program chooses the number to be guessed by selecting an int at random in the range 1–1000. The program then displays the following text in a label: A TextBox should be used to input the guess. As each guess is input, the background color should change to red or blue. Red indicates that the user is getting “warmer,” blue that the user is getting “colder.” A Label should display either “Too High” or “Too Low,” to help the user zero in on the correct answer. When the user guesses the correct answer, display “Correct!” in a message box, change the Form’s background color to green and disable the TextBox. Recall that a TextBox (like other controls) can be disabled by setting the control’s Enabled property to false. Provide a Button that allows the user to play the game again. When the Button is clicked, generate a new random number, change the background to the default color and enable the TextBox.
