Looking through boost random library I've come across literal something like 331u. Does anyone can explain to me what this u is about?
void seed(uint32_t value = 331u);Thank you

It means it's an unsigned integer, to match the type of value.
Found from the web:
u8 unsigned byte (8 bits)
u16 unsigned word (16 bits)
u32 unsigned 32-bit value
u64 unsigned 64-bit value
s8 signed byte (8 bits)
s16 signed word (16 bits)
s32 signed 32-bit value
s64 signed 64-bit value
There's more, but I'm sure you get the picture.

The type of an integer constant is the first of the corresponding list in which its value can be represented. Unsuffixed decimal: int, long int, unsigned long int; unsuffixed octal or hexadecimal: int, unsigned int, long int, unsigned long int; suffixed by the letter u or U: unsigned int, unsigned long int; suffixed by the letter l or L: long int, unsigned long int; suffixed by both the letters u or U and l or L: unsigned long int .
