Expert Solution & Answer
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.
