c++ - std::bad_alloc assigning a pointer from address of a reference -

-

for whatever reason, ended code looked this

typedef std::vector<double> vector; void f(vector const& v) {   vector const* p;   p = &v; }

this throws bad_alloc exception @ point of assignment. why? matter f called on non-cast vector? c++03 compiled on gcc 4.1.

** edit ** inside code running inside google mock see exception. tried tear code out , compile separately , worked fine. looking further

** further edit ** problem assignment happened in last line of constructor of object member of object. next object in initializer list of parent object exception coming from, gdb made happening on last line of previous object's constructor assignment taking place. downvotes remind me how misguided question was.

there no possible way code can raise std::bad_alloc exception (or other exception, matter), since doing assigning pointer value pointer variable. std::bad_alloc raised new , new[] operators when memory allocation fails, , there no such memory allocation being performed in code.

i've plotted data points , fitted exponential curve between them using 'fit' in matlab. problem fit-function got fitted line wanted plot, markers on top of regular markers. solved problem plotting wanted markers on top of unwanted couldn't seen. problem. when want show legends dots in there. how can remove markers legend without removing fitted line since both of them hidden inside fit-function? can stop 'fit' plotting unwanted markers? so, want remove blue dot called 'hoff' in picture below. you can leave out legend-entries manually leaving out handles of lines, dont want in legend. try this: %if plot something, want showing in legend, save handle: h_line = plot(x,y) %you dont want show line? dont anything, plot it: plot(mymarker) %then set legend-> can add text legend-entries %a cell-array containing strings want show up: legend([h_line another_line],{'text1' 'text2'}) with example (see comments) came solution: ...

java - Why does my date parsing return a weird date? -

-
here code using: string string = "08/07/2013".replace('/', '-'); date date = new simpledateformat("yyyy-mm-dd").parse(string); why date return: "wen jan 3 00:00:00 est 14"? not @ date format told use. edit: need format because database using requires format. the format use parse date string, not match it. using yyyy 08 . use following format: new simpledateformat("dd-mm-yyyy") and why @ replacing / - ? can build pattern original string only: string string = "08/07/2013" date date = new simpledateformat("dd/mm/yyyy").parse(string); and if want date string in yyyy-mm-dd format, can format date using dateformat#format(date) method: string formatteddate = new simpledateformat("yyyy-mm-dd").format(date); see also: change date format in java string simpledateformat java doc
