Answer 1

I like the second version better.

The while loop executes a loop 'until a condition becomes false', so whenever it's possible to find a condition, it will make the code more expressive.

The code becomes more like actual language:

'While input doesn't equal the password, ask again.'

One thing though:

Format!

Don't torment the eyes of people who have to read your code - make it readable yourself!

int x;
cout << "PIN Lock 1.0 \n\n";
do {
cout << "Please, enter PIN code: ";
cin >> x;
if (x != 60425) {
cout << "False!" << endl;
}
} while (x != 60425);
cout << "True!";
return 0;

Thanks! I'm sorry! And thanks for the tip.
I'm used to saving, even though this isn't necessary)

Answer 3

Foremost you want to save time and unnecessary effort.

Statistically people spend a lot more time reading and debugging code than actually writing it.

By choosing good formatting, you will spend a little more time now, but you may save a lot of time in the long run. 😉
