CodePudding user response:
Classmate, you I have no initialization, and you should use a long long int,Scope:
Unsigned int 0 ~ 4294967295
Int - 2147483648 ~ 2147483647
Unsigned long 0 ~ 4294967295
Long - 2147483648 ~ 2147483647
Long long: a maximum of 9223372036854775807
The minimum value: long long - 9223372036854775808
A maximum of unsigned long long: 1844674407370955161
