Assuming I have 2 variables:
uint64_t a = ...
uint32_t b = ...
Will comparing the integers yield the expected results, i.e. (a != b), or (b > a)?

int is always 32 bits wide. sizeof(T) represents the number of 8-bit bytes (octets) needed to store a variable of type T .
The long long data type makes handling 64 bit integers easy. In C language, an unsigned number over 32 bits cannot exceed the value of 4,294,967,295. You may find you are required to handle larger numbers and for this you need these numbers to be coded in 64-bit.
A 64-bit signed integer. It has a minimum value of -9,223,372,036,854,775,808 and a maximum value of 9,223,372,036,854,775,807 (inclusive). A 64-bit unsigned integer. It has a minimum value of 0 and a maximum value of (2^64)-1 (inclusive).
No problem. The compiler promotes the 32-bit to 64-bit before the comparison
