Write a program that asks the user to enter the size of a triangle (an integer from 1 to 10) Display the triangle by writing lines of asterisks The first line will have one asterisk, the next two, and so on, with each line having one more asterisk than the last line up to the number entered by the user. On the following line, write one fewer asterisk and continue decreasing the number of asterisks by 1 for each successive line until only one asterisk is displayed. (Hint: Use nested for loops; the outside loop controls the number of lines to write, and the inside loop controls the number of asterisks to display on a line.) For example, if the user enters 3, the output would be:

Write a program that prompts the user to enter apoint (x, y) and checks whether the point is within the rectangle centred at (1, 1)with width 10 and height 5. For example, (2, 2) is inside the rectangle and (6, 4)is outside the rectangle, as shown in Figure . (Hint: A point is in the rectangleif its horizontal distance to (0, 0) is less than or equal to 10 / 2 and its verticaldistance to (0, 0) is less than or equal to 5.0 / 2. Test your program to cover allcases.) Here are two sample runs. Enter a point with two coordinates: 2 2 ↵EnterPoint (2.0, 2.0) is in the rectangle

Write a program that displays a table of pounds and equivalent weights in kilograms. You can find the conversion factor online if necessary. Store this factor in a properly named constant. Allow the user to specify the range of pounds for the table by prompting for the start, stop, and step values for the pounds column. Display the pounds accurate to two decimal places centered in a column 10 characters wide. The kilometers should display accurate to three decimal places and right-aligned in a column 12 characters wide (see page 75-78). Column headings should be displayed with the same alignments. See Sample Output.

Write a program that asks the user to enter five colors. Once the user has entered the colors, your program should alphabetize them and print them to the screen. Test data: Enter the following blue yellow green purple orange Your output should be: blue green orange purple yellow

Create a program that allows the user to enter a person's age (in years) and current salary. Both Next, you plan the algorithm and then desk-check it. Figure 8-15 shows the completed IPO algorithm contains two loops. The outer loop keeps track of the three annual raise rates (3%, 4%, chart and desk-check table, which (for simplicity) uses an age of 62 and a salary of 25000ドル. The before retirement at age 65, using annual raise rates of 3%, 4%, and 5%. To calculate then for the input. In this case, the program should display a person's total earnings in Figure 8-15. You begin by analyzing the problem, looking first for the output and In this lab, you will plan and create an algorithm for the problem specification shown Frepure 8-15 Problem specification, IPO chart, and desk-check table for the retirement algorithm (continues) and 5%). The nested loop keeps track of the number of years until retirement. the amounts, the program will need to know the person's age and current salary. The...
