C++ Beginner Help

[BlueSpartan]

I am dipping my toes into the C++ waters and have come onto this challenge, but I'm stuck trying to come up with the missing code on this one. Any help would be appreciated. I'm getting to where I can usually read and follow along with a simple program but doing the construction myself is still difficult. One day at a time.

#include <iostream>
#include <string>
#include <iomanip>
using namespace std;

// Constants for array size
const int NUM_SPEAKERS = 20;

// Declaration of the Speaker structure
struct Speaker
{
                  // Speaker's name (string)
                 // Speaker's telephone number (string)
                 // Speaker's speaking topic (string)
                 // Speaker's fee for speaking (double)
};

// Function prototypes
void getInfo(Speaker &);
void showInfo(Speaker);
void showSearch(Speaker [], string, int);

int main()
{
   int maxSpeaker = 0, choice, spk;
   int count;
   string search;
   Speaker list[NUM_SPEAKERS];

   do
   {
      cout << "\n1. Enter new speaker information\n";
      cout << "2. Change speaker information\n";
      cout << "3. Display all speaker information\n";
      cout << "4. Search for a speaker\n";
      cout << "5. Exit the program\n\n";
      cout << "Enter your choice: ";
      cin >> choice;


      // Validate the menu choice.
      while (choice < 1 || choice > 5)
      {
         //Fill in code for while loop if the choice is invalid
      }

      // Process the user's choice.
      switch (choice)
      {
         // Enter new speaker information
         case 1:  
            cin.get();
            getInfo(list[maxSpeaker]);
            cout << "You have entered information for speaker ";
            cout << "number " << maxSpeaker << endl;
            maxSpeaker++;
            break;

         // Change speaker information
         case 2:  
            cout << "Speaker number: ";
            cin >> spk;
            
            // Validate input
            while (spk < 0 || spk >= maxSpeaker)
            {
               cout << "ERROR: Invalid Speaker Number\n";
               cin >> spk;
            }

            cin.get();
                                 //Call to function showinfo
                                 //Call to function getInfo
            break;

         // Display speaker information
         case 3:  
            cin.get();
            for (count = 0; count < maxSpeaker; count++)
            {
              //Write code for for loop to display speaker info
            }

         // Search for a speaker
         case 4:
            cin.get();
            cout << "Enter part of the speaker name: ";
            getline(cin, search);
            showSearch(list, search, maxSpeaker);
      }
   } while (choice != 5);

   return 0;
}

Thank you my apologies.

What is it specifically you need to know how to do, it looks like the members of that speaker struct definition need to be filled in. the comments tell you what the type needs to be and the names of the members.

 

in case 3 of a switch statement it asks you to print out to console the data in your speaker struct it appears.

 

the best advice i would give would be to read the comments thourally, the comments at the start of the methods defining what it does, write down bullet points of the main details, and go through, find where the missing code is, visualize what you would do in your known language and google the alternative in c++

 

good luck mate
