To input the user's name and the Social Security Number and print the details in different formats.

Expert Solution & Answer

Explanation of Solution

Program:

#include <iostream>
usingnamespace std;
intmain()
{
stringfname, lname; // string declared for the first name and the last name
intssn; // integer declared for the Social Security Number
cout<<"Enter your first name:\n";
cin>>fname;
cout<<"Enter your last name:\n";
cin>>lname;
cout<<"Enter your Social Security Number:\n";
cin>>ssn;
cout<<"Your details are:\n";
// details will be printed in different formats.
cout<<ssn<<", "<<fname<<", "<<lname<<endl;
cout<<ssn<<", "<<lname<<", "<<fname<<endl;
cout<<lname<<", "<<fname<<", "<<ssn<<endl;
return 0;
}

Explanation:

An 'iostream' is a header file or a pre-defined file in which cin and cout is defined.

To use the header files in the program, keyword include is written before the header file name surrounded with angular brackets.

The include keyword is always written after the '#', which is known as a preprocessor.

A preprocessor means something is being processed before the program. A preprocessor shows that the header files are processed before the program.

A 'using' is a keyword used to specify namespace or file is used with the program.

A ' namespace' is typically a container for a collection of identifiers. A namespace provides a degree of context for different identifiers, making it possible to differentiate identifiers with the same name.

C++ transferred all the standard library's features to a namespace called "std" (standard).

The cout is the keyword used to print a message or a value to the user or on the screen.

The cin keyword takes input from the user.

A main is the default name given to the main function of a program where the return type means function should return some value, here return type int is given.

In a program, the return type of the main function is int, that is, it should return an integer value. The return is considered as the exit status of an application.

I would like to get help to resolve the following case

Last Chance Securities The IT director opened the department staff meeting today by saying, "I've got some good news and some bad news. The good news is that management approved the payroll system project this morning. The new system will reduce clerical time and errors, improve morale in the payroll department, and avoid possible fines and penalties for noncompliance. The bad news is that the system must be installed by January 1st in order to meet new federal reporting rules, all expenses from now on must be approved in advance, the system should have a modular design if possible, and the vice president of finance would like to announce the new system in a year-end report if it is ready by mid-December."

2. Signed Integers Unsigned binary numbers work for natural numbers, but many calculations use negative numbers as well. To deal with this, a number of different methods have been used to represent signed numbers, but we will focus on two's complement, as it is the standard solution for representing signed integers. 2.1 Two's complement • Most significant bit has a negative value, all others are positive. So, the value of an n-digit -2 two's complement number can be written as: Σ2 2¹ di 2n-1 dn • Otherwise exactly the same as unsigned integers. i=0 - • A neat trick for flipping the sign of a two's complement number: flip all the bits (0 becomes 1, or 1 becomes 0) and then add 1 to the least significant bit. • Addition is exactly the same as with an unsigned number. 2.2 Exercises For questions 1-3, answer each one for the case of a two's complement number and an unsigned number, indicating if it cannot be answered with a specific representation. 1.
