But, take it one step at a time... You'll probably want to learn more about the basics, including functions and reading/writing to the disk before you start working on an object oriented "database".
I am already familiar with functions and variables and the other basics similiar to an event driven language, its the object oriented stuff that is new. struct - class ... Here is where I am so far in my latest learning tool...
Code:
// Hello World! V 5_00_00
// struct and class
// by SRS & the assistance of the
// fine people at cprogramming.com
* --------------------------------------------------------------------INCLUDE*/
#include <iostream> // cin/cout
//#include<iomanip>
//#include<fstream>
#include <string> // string
#include <cctype> // tolower
using namespace std;
/* ---------------------------------------------------------------------STRUCT*/
struct contacts
{
string firstName;
string lastName;
string companyName;
string homeAddress;
int id_number;
int age;
};
/* --------------------------------------------------------------------DECLARE*/
void add_someone(); // required to compile
/* ------------------------------------------------------------------FUNCTIONS*/
int yes_no() // Return 1(yes) or 2(no) or re-enter invalid answers
{
char yn;
for(;;)
{
cout << "Please enter \"Y\" or \"N\"" << endl;
string verify;
getline(cin, verify);
int verifySize = verify.size();
if((verifySize <= 0) || (verifySize >= 2)) // next line:
// User enters other than single character reply, re-enter
{
cout << "ERROR: YOUR ANSWER IS INVALID..." << endl;
cout << "Please try again..." << endl;
continue;
}
else // User enters a single character reply
{
yn = verify[0]; // Should not be necessary
yn = tolower(yn); // Force lower input
if(yn == 'y') // User enters Y or y only
{
return 1;
break;
}
else if(yn == 'n') // User enters N or n only
{
return 0;
break;
}
else // User enters any other reply, re-enter
{
cout << "ERROR: YOUR ANSWER IS INVALID..." << endl;
cout << "Please try again..." << endl;
continue;
}
}
}
}
void get_name() // Get & Verify the first and last name, offer repeat
{
string fullName;
for(;;)
{
contacts person;
cout << "Please Enter Your First Name:" << endl;
getline(cin, person.firstName);
cout << "Please Enter Your Last Name:" << endl;
getline(cin, person.lastName);
fullName = person.firstName + " " + person.lastName;
cout << "Please verify your name is correct: " << fullName << endl;
int reply = yes_no();
if(reply)
{
cout << "Hello World, from " << fullName << "!!"<< endl;
break; // Exit the loop upon verification
}
else
{
cout << "Please try again:\n" << endl;
continue; // Repeat the loop for any other answer
}
}
add_someone();
}
void add_someone() // Add a user or exit program
{
cout << "Do you wish to add a new contact now?" << endl;
int reply = yes_no();
if(reply)
{
get_name();
}
else
{
cout << "Very well, have a nice day!" << endl;
}
}
/* -----------------------------------------------------------------------MAIN*/
int main()
{
add_someone();
system ("PAUSE");
}
PLEASE ANYONE/EVERYONE with any suggestions, ideas, alternatives, improvements, post it... my feelings will not be hurt, I am eager to learn and willing to do what ever it takes...
THANK YOU ALL who have helped me learn so far, your time is GREATLY appreciated!
