Complete phonebook application program by adding saving and loading of the phone book on disk. Also each feature of the application should be in its own function.
Thank You!
-----------------------------------------------
We would like to write a phone book application with the following features.
1- Add a Phone Record: This asks user for the name and the phone number and adds it into the phone book.
2- Search By Name: This asks user to enter a name. Given the name, the program displays the phone number of the record with that name.
3- Search By Phone: This asks user to enter a phone number. Given the phone number, the program displays the name of the record with that phone number.
4- Display All: Reports all the records with their names and phone numbers on screen.

this was the code

# include <iostream>
# include < string >
using namespace std;
int main()
{
// int number [10] number can be 10, 200 ...
// int number [3] number can be (1,5,3) -- sequnce of values
// int num1; // num1 = 5 --- num1 = int
// int num2; [3]; // nu,2 = 1,5,3 ; indeces 0.1.2.3 ... n ---- num2 int,int,int -- 3 int for the intnum2
// int num2; [3];
// num2[0] = 5;
//int num2[3] = 5;
//num2[0] = 10;
//num2[2] = 15;
//for (int i = 0; i < 3; i++)
//{
// cout << num2[i] << endl;
//}
// do not want to do any math on these numbers ,, want to keep them just as is -- thats why include as string
string name[100]; // name[0], name[1], name[2], name[3], .... name[99], --- last intergere will be number of records - 1 ... so name[99]
string number[100]; // name[0], name[1], name[2], name[3], .... name[99], --- last intergere will be number of records - 1 ... so name[99]
int count = 0;
int choice;
for (int i = 0; i < 100; i++)
{
name[i] = "";
number[i] = "";
}
//name[0]<-> number[0] // parallel arrays // run parallel to each other and the values correspond
// each item inside name corresponds to each item inisde umber
