Chapter 8, Problem 11PE
Program Plan Intro
Most Frequent Character
Program Plan:
- • Declare a function named “findFrequentCharacter()” that accepts a string “my_string” as input. Inside the function,
- ○ Create a list variable “countList” to store the frequency of all alphabets.
- ○ Use the “for” loop to process all the characters in the “my_string” to check for frequency.
- ○ Inside the “for” loop,
- ■ Check if the current character “ch” is the alphabet.
- ■ If so, then find the ASCII value of the character and store it in “n”.
- ■ Check if the ASCII value of the character indicates the uppercase alphabet.
- ■ If the condition is true, then find the index of the character in the “countList” by subtracting “65” from “n”.
- ■ If the condition fails, then ASCII value of the character indicates the lowercase alphabet.
- ■ Thus, find the index of the character in the “countList” by subtracting “97” from “n” value and store it in “n”.
- ■ Using the “n” as the index, increment the value at “n” in the “countList” by “1”.
- ○ After processing all the characters in the “my_string”, declare a variable “maxVal” to hold the highest value of occurrences.
- ○ Also, declare a variable “maxValPos” to hold the position of the “maxVal” in the “countList”.
- ○ Use the “for” loop to find the highest value in the “countList”.
- ○ Inside the “for” loop,
- ■ Check if the current value is higher than “maxVal”.
- ■ If so, then update the “maxVal” with the current value and update the “maxValPos”.
- ○ Convert the “maxVal” into the ASCII value by adding “97” with it.
- ○ After that, convert the “maxVal” into character and return it.
- • Declare a function named “main()”. Inside the “main()” function,
- ○ Get a string from the user and store it in “my_string” variable.
- ○ Call the function “findFrequentCharacter()” and pass “my_string” as input to the function and store the return value in “frequentCharacter”.
- ○ Display the “frequentCharacter” using the “print()” function.
- • In the last, call the function “main()” to execute the program.

Backward String Design a program that prompts the user to enter a string and then displays the string contents backward. For instance, if the user enters "gravity" the program should display "“ytivarg."
True or False You cannot store a string in a variable of the char data type.
True or False All variables have a ToString method that you can call to convert the variable’s value to a string.
