Question

Restaurant Selector

You have a group of friends coming to visit for your high school reunion, and you want to take them out to eat at a local restaurant. You aren’t sure if any of them have dietary restrictions, but your restaurant choices are as follows:

• Joe’s Gourmet Burgers –

  • Vegetarian: No,

  • Vegan: No,

  • Gluten-Free: No

• Main Street Pizza Company –

  • Vegetarian: Yes,

  • Vegan: No,

  • Gluten-Free: Yes

• Corner Café –

  • Vegetarian: Yes,

  • Vegan: Yes,

  • Gluten-Free: Yes

• Mama’s Fine Italian –

  • Vegetarian: Yes,

  • Vegan: No,

  • Gluten-Free: No

• The Chef’s Kitchen –

  • Vegetarian: Yes,

  • Vegan: Yes,

  • Gluten-Free: Yes

Write a program that asks whether any members of your party are vegetarian, vegan, or gluten-free, and then display only the restaurants that you may take the group to. Here is an example of the program’s output:

Is anyone in your party a vegetarian? yes[Enter]
Is anyone in your party a vegan? no[Enter]
Is anyone in your party gluten-free? yes[Enter]
Here are your restaurant choices:
    Main Street Pizza Company
    Corner Cafe
    The Chef’s Kitchen

Here is another example of the program’s output:

Is anyone in your party a vegetarian? yes [Enter]
Is anyone in your party a vegan? yes [Enter]
Is anyone in your party gluten-free? yes [Enter]
Here are your restaurant choices:
    Corner Cafe
    The Chef’s Kitchen

Answer 1

As you not asked for any specific languge, I am answering in C++.

By the way, code is easy to undersatand, so you can have a idea and covert it in your own desired language.

Assumption: I am assuming, if there is a vegan guy in group then, you will say yes for both vegan and vegetarian.

Approch :

First I asked user to tell me what is your requirement(took input from console).

I used conditional statements(if-else) to consider all possible cases.

All  restaurant that satisfies group's requirement, I printed them.

#include<iostream>
#include<string>
using namespace std;
int main()
{
    string vegetarian, vegan, GlutenFree;
    cout<<"Is anyone in your party a vegetarian? ";
    cin>>vegetarian;
    cout<<"\nIs anyone in your party a vegan? ";
    cin>>vegan;
    cout<<"\nIs anyone in your party gluten-free? ";
    cin>>GlutenFree;
    if((vegetarian == "no") && (vegan == "no") && (GlutenFree == "no"))
        cout<<"Joe’s Gourmet Burgers\nMain Street Pizza Company\nCorner Café\nMama’s Fine Italian\nThe Chef’s Kitchen\n";
    else if((vegetarian == "yes") && (vegan == "no") && (GlutenFree == "no"))
        cout<<"Main Street Pizza Company\nCorner Café\nMama’s Fine Italian\nThe Chef’s Kitchen\n";
    else if((vegetarian == "yes") && (vegan == "no") && (GlutenFree == "yes"))
        cout<<"Main Street Pizza Company\nCorner Café\nThe Chef’s Kitchen\n";
    else if((vegan == "yes") && (GlutenFree == "no"))
        cout<<"Corner Café\nThe Chef’s Kitchen\n";
    else if((vegan == "yes") && (GlutenFree == "yes"))
        cout<<"Corner Café\nThe Chef’s Kitchen\n";
}

Output :

Try running above code on your own system.

Like, if this helped :)
