i'm aware of this question mentions boost's "static warning", i'd ask again, specifically, how implement static_warning operates static_assert emits warning @ compile time rather aborting compilation error. i'd similar alexandrescu's proposal static assert in pre-c++11 days somehow managed print useful contextual information part of error. it acceptable require user enable standard compiler warnings in order construction work (perhaps "invalid pointer conversion" or "breaks strict aliasing rules") -- warning should part of normal compilation anyway can used. in short, want static_warning(false, "hello world"); create compiler warning should somehow include string "hello world" in warning message. possible, in gcc , msvc, , how? i'd happily give out small reward bounty particularly clever solution. as bit of explanation: got idea when thinking this question : static warning useful way trace th...

i have small matlab script (included below) handling data read csv file 2 columns , hundreds of thousands of rows. each entry natural number, zeros occurring in second column. code taking incredible amount of time (hours) run should achievable in @ seconds. profiler identifies approximately 100% of run time spent writing matrix of zeros, size varies depending on input, in usage smaller 1000x1000. the code follows function [data] = datahandler(d) n = size(d,1); s = max(d,1); data = zeros(s,s); = 1:n data(d(i,1),d(i,2)+1) = data(d(i,1),d(i,2)+1) + 1; end it's data = zeros(s,s); line takes around 100% of runtime. can make code run changing out s's in line 1000, sufficient upper bound ensure won't run errors of data i'm looking at. obviously there're better ways this, being bashed code format data wasn't concerned. said, fixed replacing s 1000 purposes, i'm perplexed why writing matrix bog matlab down several hours. new code runs instantaneously...

this function finds first , last occurrence of integer in array. don't understand second if statement if(!found) same saying if(found==0) ? how second statement 'find' first occurrence? lets if there 3 4's in array loop finds last occurrence , sets plast , goes 2nd if statement how know find first occurrence , not 2nd occurrence? find_occurences(const int a[], size_t n, int x, size_t *pfirst, size_t *plast) { size_t i; int found = 0; for(i=0; i<; i++) if (a[i] == x) *plast = i; if (!found) { *pfirst = i; found = 1; } } return found; } in c , 0 means boolean false , , other non zero values treated boolean true . so, if (!found) go true path if found = 0 . if(!found) same saying if(found==0) ? yes is!
