I am confused about expressions, side effects, types, and values in C++? -


my teacher handed me homework assignment. beginner, i'm not sure @ start, or chart asking for. can explain me simply? teacher wants fill in type, side-effect (if applicable,) , value:

edit: why keep getting flagged down? don't understand did wrong?

it simple:

expression, part of code, something, + b

type, asking, result type of expression, can tricky in c++ :).

side-effects, statement has result type , result of sort expression can in same time update variables in process sife effects.

here example:

int = 0; int j = 0; int k = 1;  auto rslt = cout << ++i << ( j += 2) << (k *= 5);  //now type of rslt be? => &ostream, because &cout of type ostream // , used overloaded operators ostream , overloaded operator // returning ostream // hope know auto, auto leaving decision type on compiler.

on screen there be: 125 side effects:

++i // side effect of operation i:  1 (j += 2) // side effect of operation j: 2 (k *= 5) // side effect of operation k: 5

the value cout.

command line - How can a Python program background itself? -

consider following python command-line program. doesn't work because incomplete, think illustrates problem: #!/usr/bin/python3 import multiprocessing pool = multiprocessing.pool() task in expensive_iterator_with_user_interaction(): pool.call_async(expensive_computation, (task,)) pool.close() print("dear user, may press ctrl-z , bg script.") pool.join() thus, problem scripts needs user input while it's launching expensive parallel processes. there moment when user interaction not needed anymore. then, ask user background process shell actions. however, can achieved program itself? (side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now
