[ad_1] Can I make it work in my case somehow? Yes you can. You can either call it immediately after the definition: int median = [](std::vector<int> a) { std::sort(a.begin(), a.end()); return a[a.size() / 2]; }(v); //^^ –> invoke immediately with argument See for reference: How to immediately invoke a C++ lambda? or define the lambda … Read more

[ad_1] Yes, functions are located in a specific place in memory. In the context of Virtual Memory (opposed to physical caches), they are stored below the Heap and below a section called the Data (global variables) in a section called Text.

[ad_1] Because is a summer saturday and I’m happy, I’ve written a little code for you, but it’s incomplete.

[ad_1] This answer assumes reading of the earlier question and comments so is not “code only”. qt = expand.grid(Month=c(“G”,”J”,”M”,”Q”,”V”), Year=1975:2016) query_names_vec <- apply(qt, 1, function(x) paste0(“CME/GC”, paste0( x, collapse=””) ) ) > head( query_names_vec ) [1] “CME/GCG1975” “CME/GCJ1975” “CME/GCM1975” “CME/GCQ1975” [5] “CME/GCV1975” “CME/GCG1976” 10 [ad_2] solved Loop R with Quandl as optional
