Question
Chapter 9.5, Problem 9.26CP
Program Plan Intro
Tokenizing Strings:
- The tokenizing of a string denotes a process of breaking a string down into its components termed as tokens.
- The “split” method of “String” class could be used to tokenize strings.
- The character that separates tokens is termed as “delimiter”.
- The argument passed to “split” method denotes a regular expression.
- A regular expression is used to search for patterns in strings, files and other texts.
- To prevent leading or trailing whitespace characters in tokens, the string is been trimmed.
- The “trim” method of “String” class is been used for trimming purposes.
Given Code:
String str = “one two three four”;
String[] tokens = str.split(“ ”);
int x = tokens.length;
String first = tokens[0];
Explanation:
- The given code stores a string into variable “str”.
- The string is been split into tokens using “split” method.
- The count of tokens could be computed using “length” method.
- The first token in array is been stored into variable “first”.

Word Separator Write a program that accepts as input a sentence in which all of the words are run together but the first character of each word is uppercase. Convert the sentence to a string in which the words are separated by spaces and only the first word starts with an uppercase letter. For example the string “StopAndSmellTheRoses.” would be converted to “Stop and smell the roses.”

Consider the following C++ structure and declarations:
struct Player
{
string firstName;
string lastName;
int hits;
int runs;
};
int main()
{
Player p = { "Jackie", "Robinson", 1518, 947 };
Player team[24];
Player *tPtr = team;
team[0] = p;
}
What value is stored in p.lastName?
A) "Jackie"
B) 1518
C) "Robinson"
D) 947
Programming in C#:
Write a console-based application that displays every perfect number from 1 through 10000. A number is perfect if it equals the sum of all the smaller positive integers that divide evenly into it. For example, 6 is perfect because 1, 2, and 3 divide evenly into it and their sum is 6. Use format strings(field size 8, right alignment) to show all perfect numbers. Display the results as seen below.

- String Manipulation In this question, you will be implementing the following functions int findChar(char * str, char c); Searches for the character c in the string str and returns the index of the character in the string. If the character does not exist, returns -1 int replaceChar(char * str, char c1, char c2); Searches for the character c1 in the string str and if found, replace it with c2.The function returns the number of replacements it has performed. If the character does not exist, returns 0. int removeChar(char * str1, char * str2, char c); Creates a copy of str1 into str2 except for the character c that should be replaced with ‘*’ For example, if str1=”Hello World” and c=’l’ then the function should make str2=”He**o Wor*d” int isPalindrome(char * str) Checks to see if a string is Palindrome(reversible).

- Password modifier This program is: python Many user-created passwords are simple and easy to guess. Write a program that takes a simple password and makes it stronger by replacing characters using the key below, and by appending "q*s" to the end of the input string. i becomes ! a becomes @ m becomes M B becomes 8 o becomes .
