what is long long data type?

Hello @sktg99,

Datatypes specify the type, range and bytes of data a variable can store.

For 32-bit operating System:
int : 2 bytes
char : 1 byte
long : 4 bytes
long long : 8 bytes

For 64-bit operating System:
int : 4 bytes
char : 2 byte
long : 8 bytes
long long : 8 bytes

So, for 64-bit compiler, long and long long are interchangeable.

You can refer to this link for further details.

Hope, this would help.
