At 1:36, Prateek bhaiya says that the maximum number of digits we can store in long long int is 18 but I googled and the maximum digit it can store is -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807 which is 19 digits. Please help!

Hello @yajurkhurana though i have also read the same but i think you are right because i have just checked doing the same:
Okay. I googled and checked there is also some case with the unsigned long long int. Can you explain that to me?
I hope I’ve cleared your doubt. I ask you to please rate your experience here

When do we use unsigned long long int in C++?
hello @yajurkhurana
unsigned long long has higher positive range (almost double) than long long so use unsigned long long in cases where u need to store relatively higher positive number .
range of unisgned long long (64 bit system) ->
0 to 18,446,744,073,709,551,615
range of long long (64 bit system) ->
-9,223,372,036,854,775,808 to 9,223,372,036,854,775,807
Ok. Thanks you. My doubt is cleared
