C++ beginners' problem with program

Question

Hello :) i want my program to give its user 3 chances (at max) to give corect number (e.g. PIN as it is supposed to be an atm sim) and i dont really know how do i make it happen. Im thinking if the "for" loop is the correct path to take.

Answer 1

1.here size_t means unsigned int so pin can't be negative.

2.pin{1234} means pin = 1234.....same goes for _try.

3.and constexpr will just replace the values at compile time

for example after compiling the while loop will look like
while(_try != 3){....}

you will learn this things better once you start using them in your code.

Answer 2

yes , you can surely use for loop.........do you want the code or logic......did you tried anything?

Answer 3

freaxys how about this?
I currently set the pin = 1234

Answer 4

To make it clear you can use a do-while-loop:
do{
add attempt;
get number;
compare numbers;
}while(number is not epual or about 3 attempts)

Answer 5

Loops are always a good choise if you use code multiple times.

Answer 6

Tanay ay thanks man that really helps :)

Answer 7

as i said im just begining my adventure with programming so the first thing ive tried was simple if else conditionals wich i quickly erased because it felt bad to use it so then i had the idea to use switch but you cant use variables there. and now i have the idea to use loops and use maybe 'break' function in it. can i do something like that? im sorry i dont have the source code because im coding on laptop :/

Answer 8

Tanay this part of the code is new to me
