- What does the assignment of ~0u to a variable mean in C++?
Thus ~0u means the maximum value of an object of type unsigned int when each bit of its internal representation is set to 1 Consider using the operator that to set for example the first n bits to 1 The expression will look like ~( ~0u << n ) If you want to set n bits starting from m position then you can write ~( ~0u << n ) << m
- c - What does u mean after a number? - Stack Overflow
unsigned int x = 0u; This can lead to a situation where developers that deal a lot with unsigned values develop the habit of adding u suffixes to literals everywhere But, be aware that changing signedness can lead to different behavior in various contexts, for example: (x > 0) can (depending on the type of x) mean something different than (x > 0u)
- c# - Difference between 0 and 0u - Stack Overflow
The uint type is 32-bit unsigned integer type Its default value is the number 0u or 0U (the two are equivalent) The 'u' letter indicates that the number is of type uint (otherwise it is understood as int) Then is there a difference between 0 and 0u? If not, then why is the default value '0u'

@Ela782: Yep I am not sure off the top of my head, but without the u it could well be a signed long long

- What does 0u mean in c#? - Stack Overflow
Much like 0L defines 0 as a long, 0u defines 0 as an unsigned int (uint) Share Improve this
