my current struct is: typedef char airportcode[4]; typedef struct node{ airportcode airport; struct node *next; }node; my idea how function should start this: node *copy(node *list) { int count = 0; while (list != null){ count++; list = list->next; } } now know how long original list is, reason why stumped because have no idea how seperatly allocate memory each individual node have copy second list. you allocate new node malloc: node* newnode = malloc(sizeof(node)); then can change stuff inside new node with newnode->airport = <blah blah blah> newnode->next = <other node, etc etc> it might easier clone recursion rather loop, if use loop, unless lot of pointer manipulation , keep track of many nodes @ time (similar reversing linked list in place ), use stack. so this: node* clonelist(node* head){ if (!head) return null;//done node* n = malloc(sizeof(node)); n->airport = head->airport; n->n

i've been reading on sass(simply awesome stylesheets) on codeschool when tried installing it, turns out need install rvm(ruby) sass written in ruby. so have 2 questions here: i understand there other css frameworks less don't seem powerful/popular. how true this? wouldn't mind switching less if not need ruby @ all. is there compiler sass in .net or java family of languages , if there is, how production ready it? not want keep checking generated css file when debugging or making changes. this comes down want preprocessor , fits project requirements best. people argue either or day long. me see main difference in less can't many programatical things, loops, each statements. kind of thing. sass ruby based, therefore need have ruby installed. there extensions can use in visual studio make sass compiling easier. web workbench , sassy studio . support coming web essentials time soon. so think comes down think fits best. prefer use less in visua

i using subprocess.check_output() method execute commands within python script. there commands need "(double quotes) present in syntax. here's 1 example: >drozer console connect -c "run app.package.info -a com.package.name" it throws error if remove "(double quotes) above command. i did following : string = '\"run app.package.info -a com.package.name\"' command = ['/usr/bin/drozer','console','connect','-c',string] output = subprocess.check_output(command) this yields me error: *** unknown syntax: "run app.package.info -a com.package.name" please note : commands without quotes running through subprocess.check_output, code works properly. how can solve issue of quotes? highly appreciated. thanks you don’t need double quotes. the reason need them shell command shell parsing command line string, , uses them indication text run app.package.info -a com.package.name sho

is possible gnuplot print data plotted next graph? if have text file input.txt : #x y 1 2 2 5 3 6 4 7 and plot 'input.txt' i'd have plotted usual , next plot i'd have table printed. possible? note: i'm on windows , i'd format output. sure can. simplest way in gnuplot read in file calling external command ( cat on *nix, not sure on windows) , storing output variable, setting label on graph. here how it: set rmargin 8 datas = system('cat data.dat') print datas set label datas @ graph 1.1,0.7 plot 'data.dat' notitle this puts data file off side, in place of key.

i'm trying add values using loop i'm stumped how it. code have far: float counter; float harmonic; float sum; (counter = 2; counter <= n; counter ++) { harmonic = 1/counter; // current value sum = harmonic; // stores current value } return 0; } so each value "harmonic" variable need add next until loop ends. should looking @ arrays? help. change code read float sum = 0; then inside loop write sum += harmonic; you don’t need array unless want remember of values you’ve summed. also, don’t use float loop counter. want int instead.
