binary - Convert bitstring to tuple -


i'm trying find out how convert erlang bitstring tuple, far without luck.

what want example <<"{1,2}">> tuple {1,2}.

you can use modules erl_scan , erl_parse, in this answer. since erl_scan:string requires string, not binary, have convert value binary_to_list first:

> {ok, scanned, _} = erl_scan:string(binary_to_list(<<"{1,2}">>)). {ok,[{'{',1},{integer,1,1},{',',1},{integer,1,2},{'}',1}],1}

then, you'd use erl_parse:parse_term actual term. however, function expects term end dot, have add explicitly:

> {ok, parsed} = erl_parse:parse_term(scanned ++ [{dot,0}]). {ok,{1,2}}

now variable parsed contains result:

> parsed. {1,2}

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
