Chapter 3, Problem 25RQE

1. A)

Explanation of Solution

Analysis of the given code:

The purpose of the given code is to compute the monthly wages when the user enters his annual salary. The process involves in prompting the user to enter the annual salary, the entered amount is divided with the total number of months in a year. Since the variables are declared as “double” data type, the calculation process is involved with the type casting to compute the monthly wages. Finally, calculated monthly wages gets displayed...

1. B)

Explanation of Solution

Analysis of the given code:

The purpose of the given code is to perform some of the mathematical operation and display the result after processing the computations. The process includes declaration of variables using a “unsigned int” data type and assigning values for the variables. Some of the mathematical operation such as addition, subtraction and multiplication are performed and finally results are displayed.

Given Program:

// include the header

#include <iostream>

using namespace std;

C)

Explanation of Solution

Analysis of the given code:

The purpose of the given code is to define some constant values using “#define” statements and finally the program will display those values on the output screen.

Given Program:

//include the required header files

#include <iostream>

using namespace std;

//preprocessor directives for constant values

#define WHO "Columbus"

#define DID "sailed"
