help!

why doesnt this work:

Code:

---

#include "stdafx.h"
#include "iostream"

using namespace std;

int main(int argc, char* argv[])
{
        int i;
        char letter;
        char option[2];
        int x;
        do
        {
                cout << "Enter a Number: ";
                cin >> i;
                letter = i;
                cout << "\nNumber you entered: " << i;
                cout << "\nEquivalent Letter: " << letter;
                cout << "\nRestart from beginning? (Y for Yes, N for No): ";
                cin >> option;
                if(option == "N")
                {
                        return 0;
                }
        }while(option != "N");
       
}

try making it just

char letter;

i have...i still get a problem

i figured it out...all i needed was this:

Code:

---

#include "stdafx.h"
#include "iostream"

using namespace std;

int main(int argc, char* argv[])
{
        int i;
        char letter;
        char option[2];
        int x;
        do
        {
                cout << "Enter a Number: ";
                cin >> i;
                letter = i;
                cout << "\nNumber you entered: " << i;
                cout << "\nEquivalent Letter: " << letter;
                cout << "\nRestart from beginning? (Y for Yes, N for No): ";
                cin >> option;
        }while(int(option) != 78);
       
}

This does work????????
VERY strange!

The problem you have is the usual problem of C strings that so many newbies have. You can NOT use the == operator to compare strings!
A method that surely works (your method seems like a miracle to me) is this: replace
char option[2];
with
char option;
and do this:
while(option != 'N');
This tests whether the character option contains the character N (note the single braces, it means you want the character, not the string)

Always remember: it's character that counts!

yes i did that but it didnt work. Visual C++ said something about the != operator. I dont know, but i got it now. Thanks.

Code:

---

#include "stdafx.h"
#include "iostream"

You shouldn't need stdafx.h, it's only there for VC++6's personal gratification...disable precompiled headers until you know what they are (under project settings).

The "iostream" should be <iostream> since it's a system header.
