Question
(1) Prompt the user for a title for data. Output the title.
ex.
Enter a title for the data:
Number of Novels Authored
You entered: Number of Novels Authored
(2) Prompt the user for the headers of two columns of a table. Output the column headers.
ex.
Enter the column 1 header:
Author name You entered: Author name
Enter the column 2 header:
Number of novels
You entered: Number of novels
(3) Prompt the user for data points. Data points must be in this format: string, int. Store the information before the comma into a string variable and the information after the comma into an integer. The user will enter -1 when they have finished entering data points. Output the data points. Store the string components of the data points in an array of strings. Store the integer components of the data points in an array of integers.
ex.
Enter a data point (-1 to stop input):
Jane Austen, 6
Data string: Jane Austen
Data integer: 6
(4) Perform error checking for the data point entries. If any of the following errors occurs, output the appropriate error message and prompt again for a valid data point.
ex.
Enter a data point (-1 to stop input): Ernest Hemingway 9 Error: No comma in string.
Enter a data point (-1 to stop input): Ernest, Hemingway, 9 Error: Too many commas in input.
(5) Output the information in a formatted table. The title is right justified with a width of 33. Column 1 has a width of 20. Column 2 has a width of 23.
ex.
Number of Novels Authored
Author name | Number of novels
--------------------------------------------
Jane Austen | 6
Charles Dickens | 20
Ernest Hemingway | 9
Jack Kerouac | 22
(6) Output the information as a formatted histogram. Each name is right justified with a width of 20
ex.
Jane Austen ******
Charles Dickens ********************
Ernest Hemingway *********
Jack Kerouac **********************
