Chapter 3.2, Problem 3.9CP
Explanation of Solution
Given Program:
//Include the required header files
#include <iostream>
#include <cmath>
using namespace std;
//Main Function
int main()
{
//Declare the variables
double value1, value2, value3;
//Print the statement
cout << "Enter a number: ";
//Get a value from the user
cin >> value1;
//compute and store it in a variable
value2 = 2 * pow(value1, 2.0);
//compute and store it in a variable
value3 = 3 + value2 / 2 - 1;
//Print the result
cout << value3 << endl;
//Return the statement
return 0;
}
Explanation:
- Include the required header files.
- Give the “main ()” function.
- Declare the required variables.
- Get a value from the user and store it in a variable “value1”.
- Find the power value (value1^2.0), multiply it by 2 and store it in a variable “value2”.
- Do the divide operation and add the result with 3 and finally store it in a variable “value3”.
- Print the value on the screen.

ANSWER IN C PROGRAM- Consider the following structure definition and solve the following problems-
typedef struct {int phoneID; // unique ID will start from 1 up to N.char phoneName[50];int price;int ramMemory;float cpuSpeed;int gpuMemory;char userName[50];int userPhoneNo;char userCountry[50];} SmartPhoneType;
1. Write a function that will print all the information of a specific smart phone. Use the prototype -void printPhoneInfo(SmartPhoneType phoneType);
This exercise assesses the skills required to develop user defined functions, and pointers.
Exercise 2Write a C++ program to develop a Vehicle Fine Management System for Police. The program will have the following features.1. A user defined function called “Student Registration”. This function prompts a user to enter a student’s personal data i.e., Student Number, Student Name, Age and City and stores them.
2. A user defined function called “Module Enrolment”. This function takes student number from themain function as an argument and prompts a user to enter student two modules details i.e. Module name, Module Code and Module Credits Hours (15 or 30) and stores them. The programs should display an error message if a user enters credit hour other than 15 or 30.

- Book: C++ Programming: From Problem Analysis to Program Design 8th edition, D. S.

For simplicity, assume that the bank offers three types of accounts: savings, checking, and certificate of deposit, as described next. Savings accounts: Suppose that the bank offers two types of savings accounts: one that has no minimum balance and a lower interest rate and another that requires a minimum balance and has a higher interest rate. Checking accounts: Suppose that the bank offers three types of checking accounts: one with a monthly service charge, limited check writing, no minimum balance, and no interest; another with no monthly service charge, a minimum balance requirement, unlimited check writing, and lower interest; and a third with no monthly service charge, a higher minimum requirement, a higher interest rate, and unlimited check…arrow_forwardDefine a structure type to represent a common fraction.
