Textbook Question

Chapter 2, Problem 2.7E

Discuss the meaning of each of the following objects:
a) std: :cin
b) std: : cout

(a)

Expert Solution

To determine

To discuss the meaning of std::cin.

Explanation of Solution

cin is an object which is used to read the data from input devices in a C++ program. Here, std is the standard I/O reader. It needs “iostream” header file to be included with preprocessor as #include<iostream>.std::cin is normally connected to the keyboard to input data. Data is inputted by a concatenating stream extraction operator (>gt;).

So, std::cin is used to read input from the user.

(b)

Expert Solution

To determine

To discuss the meaning of std::cout.

Explanation of Solution

cout is an object which is used to write the output to the console in a C++ program. Here, std is the standard I/O reader. It needs “iostream” header file to be included with preprocessor as #include<iostream>.std::cout is normally connected to screen to output the data.std::cout indicates that the cout is used from “namespace ” std. Data is outputted by a concatenating stream insertion operator (<<).

So,std::cout will send the stream of characters to the standard output stream object.
