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

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)

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.

You will need to understand 2's Complement todetermine when the input 4-bit binary number corresponds to a negative or positive number. To understand how anLED display works in Digital, please refer to the playWithLED_Display.dig file provided. You should play withdifferent input combinations to see how it influences the LED Display value. In the screenshot below, note how I wasable to generate the display of “3” on the Hex display by lighting up only certain input wires to the unit. Here is a picture of how the different segments light up to produce the different displays: Note in the picture above that we showed displays only from 0-8 since in 4-bit 2s complement representation, 8 is thelargest modulus value you can represent (the range of integers would be -8 to +7).Your circuit in Part-2 must accept a 4-bit 2's complement input {in3, in2, in1, in0} where in3 is the most…arrow_forwardSolve this "Do not use AI tools.
