Question

x.Hmking on a program and in a text file I added 1111 to make it an acceptable pin number but when i enter 11111 it is recognized as a valid pin number. I tried 1112 and returned an error as it is supposed to so that is correct. I will give the code that you may need to look at because my code has gotten too big...I am first going to give you my int main code then code of asking for a pin number

//Begin coding the program
#include <iostream>
#include <iomanip>
#include <time.h>
#include <fstream>
#include <conio.h>
#include <string>

using namespace std;

//Function prototypes
void showMenu();
int mainMenuSelection(int);
void welcomeScreen();
double enterAmountScreen(double);
int anotherTransactionScreen(int);
void goodbyeScreen();
void wait(int);
int dataEntryScreen();
void timeStamp();
//void withdrawMax();

*/

int main ()
{
    //Declare variables
    int choice;
   
    //Set the numeric output formatting
    cout << fixed << showpoint << setprecision(2);

    //Function for welcome screen
    welcomeScreen();

    //Give space for the function of date and time
    cout << endl << endl;

    //Prompt to show today's date
    cout << "Today's date is: " << endl;

    //Show date and time function
    timeStamp();

    //Enter some space
    cout << endl << endl;

    //Function to enter a pin number
    choice = dataEntryScreen();

    //if statement for choice
    if (choice == -1)

        //Return a value
        return 0;

    //Create a dowhile loop
    do
    {
        //Display the menu and get the user's choice.
        showMenu();
        cin >> choice;

        //Validate the menu selection.
        while (choice < 1 || choice > 5)
        {
            //Prompt user to reenter a correct choice
            cout << "Please enter 1, 2, 3, 4, or 5: ";
            cin >> choice;

            //add color to error message
            //add color to error message
            system ("Color 3a");
        }
       
        //Function to choose in the main menu selection
        mainMenuSelection(choice);

    //End the while statement
    } while (choice != 5);
   
    //Function returns a value
    return 0;
}

Here is my pin number information...

int dataEntryScreen()
{
    //Declare variables
    bool found;
    string valid;
    char pin[4];
    int pinChoice,
        i,
        j;
    ifstream Input;

    //Perform dowhile loop to check for correct validation
    do
    {
        //Display the output
        cout << " Data Entry Screen";
        cout << endl << "1) Enter pin number";
        cout << endl << "2) Exit the ATM";
        cout << endl << "Please enter a selection: ";
        cin >> pinChoice;

        //add color to background of data entry screen
        //add color to text of data entry screen
        system ("Color 3c");

        /*

        while (pinChoice < 1 || pinChoice > 2)
