go - map of map of structs and "assignment to entry in nil map" -


here's example assignment entry in nil map every time: https://play.golang.org/p/ludjs0rvbs

to demonstrate i'm trying do, here's naive version causes 2 lookups database (you'll have use imagination on line 11): https://play.golang.org/p/yznfemhyms

basically, i'm trying this:

things := make(map[string]map[string][]struct) ... stuff, there := things["first key"] if !there {     things["first key"] = getamapofstringtostructs() } dosomethingwith(things["first key"])

i've looked @ more trivial examples of maps-of-maps here can't seem map problem.

you never did make on allentries map:

allentries = make(map[string]map[string][]thing)

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.
