WebNov 16, 2024 · First of all rand returns int and not unsigned int, and if your unsigned int is 32 bits, then bit shift left to position 17 is invalid if top bit is set. The second problem is that if rand indeed does return more than 15 bits then you're getting too many. WebApr 11, 2024 · April 11, 2024.
