who else noticed the "and" at 6:20 :p
this shows how much she is committed into helping us learn efficiently
thanks alot code beauty
this channel helped me alot to get through my finals at uni

[OMG_Tv]

I'm so thankful I found this channel, because it simple and clear to understand how they explain the program

[isaabe]

thank you very much indeed ! it is so amazing tutorial

[aasifali]

thx a lot for this video. it cleared all my doubts.

[wattstudio]

Fun project! I might expand on this one later.

[momomunsta]

I added the ability to choose your pin aswell as telling the user how many attempts they have left! These tutorials have been so useful and easy to learn from. Thanks you!

[IAmIshanSaxena]

This application is very useful, we can even access our very sensitive data using
Great

[KAIzoKUxxx]

Great explanation and easy to understand. You should really consider to be a full time lecturer. I would love to be your student😁

[christianmaverickbautista]

Hi, Ms. code! I'm an aspiring game developer and am attempting to learn C++. Currently, I watch your vids, because they are the most up-to-date tutorials I can find and I find your way of teaching very comprehensible. I usually attempt to create the program right after you give the general discussion, and would like to know if my codes are passable.

int pin, input, attempts = 0;

cout << "Creat PIN: ";
cin >> pin;
attempts += 3;
system("CLS");

do {
cout << "Enter PIN: " << endl;
cout << attempts << " attempts left" << endl;
cin >> input;


attempts--;
system("CLS");
if (pin == input)
cout << "Account accessed";
} while (pin != input && attempts > 0);

if (attempts == 0)
cout << "Access Denied";

I love how she teaches really friendly smoothly and lovely she is better than our programming lecturer 🥰😍

Hello, i am getting the concept now but for the while loop on reversed number i don't get well and this is due to some of the source codes declared example int lastDigit = number % 10; and number = number / 10;. can you explained better for while these. Thank you.

Marry me :D Šalim se, puno pozdrava za tebe, studirao sam na FIT-u i jednim dijelom savladao C++ ali me posao odveo u drugom smjeru tako da sam zapostavio. Ovo će mi svakako dobro doći da osvježim zaboravljeno znanje. Puna podrška & keep it up!

Hey Saldina. I have a question. i was trying to run do while loop in eclipse. and its showing error and not taking void main() instead asking for int main() while your code ran without any errors. i copid the same code as yours. what is happening?

[digitalturan]

İ did not get why we have not used curly brackets in if...else

[francisc.t.]

Hi, im entering competitive programming and i've heard that the best language for it is C++, until what kind of certain level of the C++ language to be able to get comfortable with Competitive Programming?

[kelvinvelazquez]

In this program I assigned a pin for the user, Pin :1234, I want the user to put the pin and the program creates memory, or assigns a memory when the program runs again, so the user does not need to enter the pin again

[jamieMcSorley-ci]

I noticed if I enter a letter or a symbol, the program immediately runs through the code asking to enter the pin, but doesn't allow a pin to be entered, then the program defaults to "Blocked". Is there a way to debug this? I was thinking of using another if statement

[vijayshankarshukla]

Why are you used here void main() function?

[Geoffroxx]

When I type in else it throws an error even if I have typed in the code verbatim to yours, int userPin = 1234, pin, errorCounter = 0;

do{
cout << "PIN:";
cin >> pin;
if (pin != userPin)
errorCounter++;

} while (errorCounter< 3 && pin!= userPin );

if (errorCounter < 3);

cout << "Loading";

else

cout << "Blocked";
