Explanation of Solution
Given: The following lines of code that contains a list box in which the font of the output is set to ‘Courier New’:
Dim fmtStr As String = "{0,-7} {1,-7:N1} {2,-7:P1}" 'Two spaces IstOutput.Items.Clear()
IstOutput.Items.Add("12345678901234567890") IstOutput.Items.Add(String.Format(fmtStr, "Element", "Weight", "Percent")) IstOutput.Items.Add(String.Format(fmtStr, "Oxygen", 97.5, 97.5 / 150)) IstOutput.Items.Add(String.Format(fmtStr, "Carbon", 27, 27 / 150))
To find: The output produced by the given lines of code.
Dim fmtStr As String = "{0,-7} {1,-7:N1} {2,-7:P1}" 'Two spaces IstOutput.Items.Clear()
IstOutput.Items.Add("12345678901234567890") IstOutput.Items.Add(String.Format(fmtStr, "Element", "Weight", "Percent")) IstOutput.Items.Add(String.Format(fmtStr, "Oxygen", 97.5, 97.5 / 150)) IstOutput.Items.Add(String.Format(fmtStr, "Carbon", 27, 27 / 150))
Solution:
The given lines of code will show “123456789012345678901234567890 Element Weight Percent Oxygen 97.5 65.0 % Carbon 27.0 18.0 %� as output in the list box named “IstOutput� because the method named “Add� will add the items to the list. The value “123456789012345678901234567890� will be concatenated with “Element�, “Weight�, “Percent�, "Oxygen", "97...

Maximum Occurring Character Given a string, return the character that appears the maximum number of times in the string. The string will contain only ASCII characters, from the ranges ('a'-'z','A'-'Z','0'-'9'), and case matters. If there is a tie in the maximum number of times a character appears in the string, return the character that appears first in the string. Example text = abbbaacc Both 'a' and 'b'occur 3 times in text. Since 'a'occurs earlier, a is the answer. Function Description Complete the function maximum Occurring Character in the editor below. maximumOccurringCharacter has the following parameter: string text: the string to be operated upon Returns char: The most occurring character that appears first in the string.

- Problem Description: Standard telephone keypads contain the digits zero through nine. The numbers two through nine each have three letters associated with them (Fig. 1). Many people find it difficult to memorize phone numbers, so they use the correspondence between digits and letters to develop seven-letter words that correspond to their phone numbers. For example, a person whose telephone number is 686-2377 might use the correspondence indicated in Fig. 1 to develop the seven-letter word “NUMBERS.” Every seven-letter word corresponds to exactly one seven-digit telephone number. A restaurant wishing to increase its takeout business could surely do so with the number 825-3688 (i.e., “TAKEOUT”). Fig. 1: Telephone keypad digits and letters. Every seven-letter phone number corresponds to many different seven-letter words, but most of these words represent unrecognizable juxtapositions of letters.
