performance - call to condition on for loop (c++) -

here simple question have been wondering long time : when loop such 1 : for (int = 0; < myvector.size() ; ++i) { // loop } as condition i < myvector.size() checked each time, should store size of array inside variable before loop prevent call size() each iteration ? or compiler smart enough ? mysize = myvector.size(); (int = 0; < mysize ; ++i) { // loop } and extend question more complex condition such i < myvector.front()/myvector.size() edit : don't use myvector inside loop, juste here give ending condition. , more complex condition ? the answer depends on contents of loop–it may modify vector during processing, modifying size. however if vector scanned can safely store size in advance: for (int = 0, mysize = myvector.size(); < mysize ; ++i) { // loop } although in classes functions 'get current size' inline getters: class xxx { public: int size() const { return msize; } .... private: int msize; ...

ios - Automatically set UIView vertical size based on device vertical size (including Auto Layout changes) -

i've been googling on , can't seem pinpoint answer question have. i'm writing app , vertical space of child uiview maintain height of device or rotation of parent device regardless of orientation , without hardcoding values ahead of time. the structure of layout is: viewcontainer uiview uiscrollview uiview (content view) specifically, have vertical space of content view set native height of device/orientation running on, , when device rotates, vertical space change new vertical height. uiscrollview used pan horizontally only. i using quartz draw in view. set initial height via intrinsiccontentsize ? if how query parent view? i've tried using self.superview within content view doesn't work. how detect change has occurred, , after occurs, how new y resolution , apply it? not want disable auto layout if don't have to. here visual of want if haven't made clear: https://www.evernote.com/l/aai3vfkkbarplypsourjowamiigielf5p-w ...

java - Trouble writing 's into a .txt file, using FileOutputStream -

the problem when read string , then, try write each characters in separate line, .txt file, although system.out.println show correct characters, when write them .txt file, 's write weird characters instead. illustrate, here example: suppose have line second subject’s layout of same 100 pages. , want write .txt file, using following code: public static void write(string swrite) throws ioexception { if(!file.exists()){ file.createnewfile(); } fileoutputstream fop=new fileoutputstream(file,true); if(swrite!=null) for(final string s : swrite.split(" ")){ fop.write(s.tolowercase().getbytes()); fop.write(system.getproperty("line.separator").getbytes()); } fop.flush(); fop.close(); } the written file word, subject's : subjectâ€™s . have no idea why happens. try following. frees having deal character encoding. printwriter pw = null; try { pw = new printwriter(file); if (swrite!=null) ...

matlab - How to do bitwise operation decently? -

i'm doing analysis on binary data. suppose have 2 uint8 data values: a = uint8(0xab); b = uint8(0xcd); i want take lower 2 bits a , , whole content b , make 10 bit value. in c-style, should like: (a[2:1] << 8) | b i tried bitget : bitget(a,2:-1:1) but gave me separate [1, 1] logical type values, not scalar, , cannot used in bitshift operation later. my current solution is: make a|b ( a or b ): temp1 = bitor(bitshift(uint16(a), 8), uint16(b)); left shift 6 bits rid of higher 6 bits a : temp2 = bitshift(temp1, 6); right shift 6 bits rid of lower zeros previous result: temp3 = bitshift(temp2, -6); putting these on 1 line: result = bitshift(bitshift(bitor(bitshift(uint16(a), 8), uint16(b)), 6), -6); this doesn't seem efficient, right? want (a[2:1] << 8) | b , , takes long expression value. please let me know if there's well-known solution problem. that or equivalent addition when dealing integers result = bitshif...
