i'm experiencing huge load times firebase. have 5,000 entries in "users" collection, , working fine until added base64-encoded photo each user. here's summary of code: function initcurrentauth() { return authref.$requireauth().then(attachuserobject); } function attachuserobject(authdata) { getuser(authdata.uid).$loaded().then(function(user) { ...this code never runs because getuser never resolves } } function getuser(id) { userreference = usersref.child(id); return $firebaseobject(userreference); } i'm on free firebase plan, i'm wondering if i'm being throttled? if has insights, appreciated. thanks! not sure if else, in case - frank suggested, did have "listener". had been looking $watch in code trigger it, had $firebaseobject(users) call triggered massive download.

my question regarding finding factorial of number using ternary operator in c. code below suggests using recursion, in not function definition, argument list . valid in c ? [note : 0 factorial handled seperate piece of code] the function prototype fact : int fact(int); the definition : int fact(num=(num>1)?num*fact(num-1):1) { return num; } my question is, recursion different instance of same function called within function, can true arguments ? you want this: int fact(int num) { return num > 1 ? num*fact(num-1) : 1; }

this question has answer here: how implement big int in c++ 16 answers i have 2 strings, both contain numbers. numbers bigger max of uint64_t . how can still add these 2 numbers , convert result string? well, can either use bigger datatype (for example library deals large integers), or can knock own. i suggest if 1 off, long addition have learned in first few years of school. can operate directly on 2 strings, add columns, 'carry', , build string containing result. can without conversion or binary. here. fun, knocked solution you: string add( const string& a, const string& b ) { // reserve storage result. string result; result.reserve( 1 + std::max(a.size(), b.size()) ); // column positions , carry flag. int apos = a.size(); int bpos = b.size(); int carry = 0; // add columns while( carry > 0
