Thread: Making an address book in C++ with arrays inside of structures?

I am trying to make a program that

1) Ask how many positions the user would like
2) Prompt a list of address book questions for them to fill in the data
3) ask which position to view
4) show all of the information in that position

Basically I am thinking of making an array. They input how many elements to make in it. it then asks a list of questions I made in a structure and then asks which element to view and when they pick an element it shows the entire thing. This is what I have so far:

Code:

#include <cstdlib>
#include <iostream>

using namespace std;

int main(int argc, char *argv[])
{   
    int entries;
    cout<<"How many entries would you like?  ";
    cin>>entries;
 
 
 struct person
      {
            string phoneNumber;
            string wholeName;
           /* string address;
            string DOB;
            string eMail;
            string favoriteShow;
            string city;
            string state;
            string zip;
            string myspace;
            string favoriteFood;
            string gamerTag;
            string hairColor;
            string organDonar;
            string salary;
            string employer;
            string placeOfBirth;
            string mothersMaiden;
            string teacher; 
        */     };
    

    int i;
    for (i=0; i<entries; i++)
{    
  
    int myArray[entries]; 
            
            
            person info;
            
            cout<<"Enter Phone Number:  ";
            cin>>info.phoneNumber;
            cout<<endl;
            
            cout<<"Enter Whole Name:  ";
            cin>>info.wholeName;
            cout<<endl;
            


}
    
    system("PAUSE");
    return EXIT_SUCCESS;
}

As you can see for now I am just working with the first two entries in the structure to see if I can get it to work.

I think I am on the right track but

struct myArray[entries];

gives me an error and only works when it is

int myArray[entries];

but shouldn't it be struct since I am putting a structure into the array and not an integer?

Please help!

I would love for someone to just do the entire thing for me so I can learn from it and don't have to beat my head against the wall anymore, but any help is appreciated. =]

Another possible solution for beginners besides a vector is to have a max size set as a constant. You can then use that max size for your array declaration and keep a separate variable to store the number of actual entries. You just have to make sure the number of entries is never greater than the max size.

Note that the instructions in the assignment usually make it clear whether this approach is appropriate. You can also ask your instructor if there is some maximum number of entries allowed.
