C on Windows vs Linux - differences -

-
this code works on windows (visual studio), on linux gcc, produces incorrect results. can spot issues? work differently on linux vs windows? is there way of compiling on linux? rather working gcc, if can me spot issues in code act differently on linux, great. - returning this: char output[8]; char *x = output; return x; for one, have plenty of code returns pointers local arrays, not allowed , cause undefined behavior when pointers de-referenced later. if code works in windows, you're being lucky since code not valid. the 2 typical solutions are: have caller pass in pointer (and size_t length value prevent overwrite, of course!) string space called function allowed work. dynamically allocate new memory string inside function , return that. becomes caller's responsibility free() memory when it's no longer needed.

-
i have matrix containing several "list" vector. transform them numerics. have read should use as.numeric(x) - since have several values use function goes through matrix , checks each vector of matrix if list , returns numeric. i have thought use like: if typeof(matrix$vector1)=="list" then as.numeric(matrix$vector1) can me out how create such function? i'd appreciate kind of help! kind regards, try this: if (is.list(matrix$vector1)) sapply(matrix$vector1,as.numeric) is.list check whether input list, if true sapply 'apply' function as.numeric every element of list

javascript - Emulating private methods with closures vs public methods in objects -

-
as mdn states closures used emulate private methods module pattern : var counter = (function () { var privatecounter = 0; function changeby(val) { privatecounter += val; } return { increment: function () { changeby(1); }, decrement: function() { changeby(-1); } }; }()); however, instead of using module pattern can create class instead. advantage of creating class on using module pattern? function counter() { var privatecounter = 0; function changeby(val) { privatecounter += val; } this.increment = function() { changeby(1); }; this.decrement = function() { changeby(-1); }; } var counter = new counter(); what advantage of creating class on using module pattern? the advantage of creating class on using module pattern can create several instances of class: var counter1 = new counter; var counter2 = new counter; each inst...

python - List to str adding backslash \ to string using str() -

-
i trying extract file paths txt file. file says c:\logs. use with open(pathfile, "r") f: pathlist = f.readlines() to produce list path in, , then path1 = str(pathlist) to produce line string. list sees line in th efile, te second command puts in backslash: c:\logs. i os.chdir(path1) to @ path , error windowserror: [error 123] filename, directory name, or volume label syntax incorrect: "['c:\\logs']" why this? how can prevent it? i looking have many paths in file , have script search each path individually. best way it? thank much. the backslash see "escape" character, how representation of string disambiguates existing backslash. it's not 2 backslashes the problem pathlist list , , you're forcing str . instead, take first element of pathlist: path1 = pathlist[0] you may have line break @ end (another use of escape: \n or \r ). solve that, use .strip() path1 = pathlist[0].strip()
