A)

Explanation of Solution

Stream manipulator:

In C++, a stream manipulator is used to format outputs, but it can also be used to control the character length that “cin >>” on its next read.

Example:

Consider the below example to illustrate how stream manipulator is used to control the “cin >>” inputs:

Char student_name[5];

cin >> setw (5) >> word;

Explanation:

Here the data type “char” is defined first and it is followed by the variable name “student_name”.

The “[5]” is referred as “size declarator”. It indicates how many characters it can hold in memory cells...

B)

Explanation of Solution

“getline” function:

The “cin.getline” function is used to a read string containing white spaces. It will read characters until it reaches the maximum specified number provide in the function.

Example of using getline function to control cin inputs:

cin.getline(wrd,10);

Here, the variable “wrd” is referred as C-string name which can hold 10 characters...

3. Word Counter Write a function that accepts a pointer to a C-string as an argument and returns the number of words contained in the string. For instance, if the string argument is "Four score and seven years ago" the function should return the number 6. Demonstrate the function in a program that asks the user to input a string then passes it to the fune- tion. The number of words in the string should be displayed on the screen. Optional Exercise: Write an overloaded version of this function that accepts a string clás object as its argument.

Write a function that searches for a particular character in a string using the following header: void search(string& s, char& key) Write a test program that prompts the user to enter the string and a character and displays if the character is found.
