Question

Using C++ programming.

This exercise will test your knowledge of passing structures to functions. Create a structure that stores information about various plumbers that you are getting repair estimates from. As you can see from the output, the structure must store the name, phone number, and estimate. Since you are only getting estimates from two companies, only two structure variables are needed.

Functions:

1) Get data from the user. This function must be called TWICE.

2) Print the summary you see in the last line of output. The formula is simple: Check which company has the lower estimate and output their name and the difference in price. If they gave the same estimate, then output a message stating so.

Output:

This program will compare estimates from two different plumbers.

Enter the company/plumber name: [user types: ABC Corp]

Enter the phone number: [user types: 305-555-1111]

Enter the estimate received: [user types: 90]

Enter the company/plumber name: [user types: XYZ Corp]

Enter the phone number: [user types: 305-555-2222]

Enter the estimate received: [user types: 99.50]

ABC Corp is cheaper by $9.50

(Could also have been this: "Both plumbers gave the same estimate. Go with either.")

Notes and Hints:

1) Since the company / plumber name can have a space in it, you must use GETLINE for this piece of input. Important: Remember to use std::cin.ignore() near the end of the function. Otherwise, the next time the function is called, getline will read the leftover newline from the previous input.

Answer 1

In this C++ Program,

- We have defined a structure named Company which contains member variables:
1. string name;
2. string phone_number;
3. double estimate;

- We have defined a function named getDetails to accept input from the user to initials the structure variables.

- In main, we have declared 2 structure objects called c1 and c2 and calling the getDetails() to initialize those structure objects.

- Then we are comparing the estimate of both the structure objects and printing the respective message to the console.

(I believe that the logic which I used is simple and easy, If you still have any query, Feel free to drop me a comment below)

Program:

#include <iostream>
using namespace std;

//Company structure declaration
struct Company
{
string name;
string phone_number;
double estimate;
};

//Function prototype
Company getDetails();

//Function getDetails() definition
Company getDetails()
{
Company c;//delared structure object
  
//Prompting the user to enter details
cout<<"Enter the company/plumber name: ";
std::getline(cin,c.name);
cout<<"Enter the phone number: ";
cin>>c.phone_number;
cout<<"Enter the estimate received: ";
cin>>c.estimate;
std::cin.ignore();
//Returning the structure object
return c;
}
int main()
{
//Created 2 structure objects of Company
Company c1,c2;
  
//Calling the getDetails() to get the data from the user
c1=getDetails();
c2=getDetails();
  
//Company1's estimate is less
if(c1.estimate<c2.estimate)
{
cout<<c1.name<<" is cheaper by $"<<(c2.estimate)-(c1.estimate);
}
//Company2's estimate is less
else if(c1.estimate>c2.estimate)
{
cout<<c2.name<<" is cheaper by $"<<(c1.estimate)-(c2.estimate);
}
//Both estiamtes are equal
else
{
cout<<"Both plumbers gave the same estimate. Go with either.";
}
return 0;
}

main.cpp #include <iostream> 2 using namespace std; 4 //Company structure declaration struct Company string name; string phone_number; double estimate; }; //Function prototype 13 Company getDetails(); 14 //Function getDetails() definition Company getDetails() 17 - { Company c;//delared structure object //Prompting the user to enter details cout<<"Enter the company/plumber name: "; std::getline(cin,c.name); cout<<"Enter the phone number: "; cin>>c.phone_number; cout<<"Enter the estimate received: "; cin>>c.estimate; std::cin.ignore(); //Returning the structure object return c; 30 } 31 int main() 32 { //Created 2 structure objects of Company Company c1,c2; 33 //Calling the getDetails() to get the data from the user c1=getDetails(); c2 getDetails(); //Companyi's estimate is less if(c1.estimate c2.estimate) cout<<c1.name <<" is cheaper by $"<<(c2.estimate)-(c1.estimate);

//Company2's estimate is less else if(c1.estimate c2.estimate) cout<<c2.name<<" is cheaper by $"<<(c1.estimate)-(c2.estimate); 49 //Both estiamtes are equal else cout<<"Both plumbers gave the same estimate. Go with either."; return 0;

Output:

Enter the company/plumber name: ABC Corp Enter the phone number: 305-555-1111 Enter the estimate received: 90 Enter the company/plumber name: XYZ Corp Enter the phone number: 305-555-2222 Enter the estimate received: 99.50 ABC Corp is cheaper by $9.5 ...
