Understanding Numeric Literals with ULL Suffix
In C/C programming, numeric literals can be specified with various suffixes to indicate their integer data type and size. One such suffix is "ULL," which you encountered in the code snippet:
line += addr & 0x3fULL;
Indeed, "ULL" stands for "Unsigned Long Long." It suggests that the numeric literal "0x3f" should be interpreted as an unsigned long long int.
According to the C standard library, adding the "ULL" suffix to an integer constant denotes an unsigned long long int type. This suffix is introduced to support integers with a width of at least 64 bits.
Using ULL for Unsigned Long Long Integers
In the provided code example:
Conclusion
The "ULL" suffix for numeric literals allows you to represent large integers with an unsigned long long data type. It is essential for handling numbers that exceed the range of standard integer types, ensuring accurate representation and avoiding overflow errors.
