Address Book

[Javier Medina]

Hello, this program is an address book where you caan add/view entries. I'm having a problem printing out entries. Can someone help me find out why the information isn't getting saved into the structure array?

#include <iostream>
#include <string>


using namespace std;


struct contactinfo
{
    string name, phonenumber;
    int age;
};


int menu();
void addentry(contactinfo,int);
void viewentry(contactinfo,int);


int main()
{
    menu();
    return 0;
}


void addentry(contactinfo contact[],int index)
{
    char ch;
    int size=10;


    cout<<"\nEnter contact name: " ;
    getline(cin, contact[index].name,'\n'); 
    cout<<"\nEnter contact age: " ;
    cin>> contact[index].age; cin.ignore();
    cout<<"\nEnter contact phone number: ";
    getline(cin, contact[index].phonenumber,'\n');






    cout<<"\nWould you like to add another entry? [Y/N]\n";
    cin>>ch; cin.ignore();


    switch(ch)
    {
    case 'y':
        {
            if ((index+1)==size)
            {
                cout<<"\nYour address book is full.";
                break;
            }
            else
                addentry(contact, (index+1));
                
                break;
                        
        }
    case 'n':
        menu();
        break;
    default:
        cout<<"\nInvalid Input";
        menu();
        break;
    }
    return;
}


void viewentry(contactinfo contact[], int size)
{
    for (int i=0;i<size;i++)
    {
        cout<<"\n" <<contact[i].name <<endl <<contact[i].age <<endl <<contact[i].phonenumber <<endl;
        
    }
    getchar();
    
}


int menu()
{
    const int size=10;
    int ch;
    int index=0;
    contactinfo contact[size];




    cout<<"Address Book\n\n\t[1]Add a new entry\n\t[2]View previous entries\n\t[3]Exit Program\n\n" ;
    cin>>ch; cin.ignore();


    switch(ch)
    {
    case 1:
        addentry(contact,index);
        break;
    case 2:
        viewentry(contact,size);
        break;
    case 3:
        return 0;
        
    default:
        cout<<"\nInvalid Input\n\n";
        menu();
        break;


    }
    return 0;
}

Be careful of all those recursive calls to menu. When you call menu() recursively the local variables are re-created each time you enter the function. I suggest you investigate loops and letting the functions return to their calling function when they're finished.
