Chapter 3, Problem 3RQE

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...
