it's first time posting iphone app apple. after research have not been able find out answer questions , don't want app bounced due silly thing. referring link below create images/icons: icons/image diamensions the 2nd last line on link says "the standard bit depth icons , images 24 bits—that is, 8 bits each red, green, , blue—plus 8-bit alpha channel." mean total bit depth should 32? i have of images in app bit depth less 32. question are there chances app rejected because of this? must have images/icons of bit depth 32? my last icons submitted described "24 bit" , didn't have alpha channel. app accepted. (it submitted , accepted in february of 2014) looking @ of our icons , screens, 24 bit. we've submitted half dozen apps 3 or 4 times each. none of them failed or questioned.

suppose have vector v of length n ; wish create new vector of length, contain na in first k cells, , in cell number m contain difference v[m]-v[m-k] . i can create for-loop accomplishes task: diffs <- rep(na, length(v)) (i in k+1:length(diffs)) { diffs[i] <- v[i] - v[i-k] } but i've heard loops in r slow, , looks bit cumbersome that. actually, goal create list of diff vectors , not single 1 - 1 each k in range. loops solution? example on input v <- 1:5 , k=2 i'd expect output [1] na na 2 2 2 (however, turns out, output of snippet above [1] na na 2 2 2 na na ...) ?diff vec <- data.frame(v=c(1,3,5,15,21)) vec$dif <- c(na, diff(vec$v, lag = 1, differences = 1)) > vec v dif 1 1 na 2 3 2 3 5 2 4 15 10 5 21 6 for other lag interval or magnitude of differences, change lag , differences arguments accordingly

i have following constellation: class base {...}; class derived : public base { public: unsigned int* a; derived(size_t num = 1) : a(0), _b(0) { = new unsigned int[num]; _b = new unsigned char[num]; } private: unsigned char* _b; } all fine doing this: derived* instance = new derived(); but doing this: base* instance = new derived(); _b stays 0x0 , errors occur later when try use _b. what happening here? update: the problem caused windows / linux cross platform issue - values filled incorrect pointers. first: why need initialize a , b twice? use explicit initialization only, or standard member initialization not both... derived(size_t num = 1) : a(new unsigned int[num]), _b(new unsigned char[num]) { } this should trick. second: if create instance of derived base , members , functions of derived useless. except members , functions of base, common in both classes.
