Similarly, the global C++ std::cin variable of type <iostream> provides an abstraction via C++ streams.
sudo is unable to pipe the standard output to a file. By dumping its stdout stream into /dev/null , we also suppress the mirrored output in the console.

Instruction 2 would be fetched at t 2 and would be complete at t 6. The first instruction might deposit the incremented number into R5 as its fifth step (register write back) at t 5. But the second instruction might get the number from R5 (to copy to R6) in its second step (instruction decode and register fetch) at time t 3. It seems that the ...
