possible duplicate: difference between 'global' , 'static global' what difference between statements 1 , 2 :- #include <stdio.h> //in global declaration area static int a; // 1. int b; // 2. thanks help. a static global variable local translation unit defined in. so, if define static int a; in 2 different translation units, create 2 independent variables. if define non-static global variable int b; in 2 translation units, experience linker error (but can use extern int b; in 1 of 2 translation units tell linker should use global variable other translation unit).

(2) overkill use try, catch, throw simple (i improve style)? (3) if there error, terminate program. how that? or "catch" mean that done automatically? (4) don't understand use of cerr. why not use cout? have used cerr correctly here? should have used in if/else statements? thanks lot help. here's example made: double calculated = 10.2; // previous calculation double tolerance = 0.3; // can set in function double valuewanted = 10.0; // previous calculati...

c++ - Returning array -

how return pointer array , values that? int * getchange(int first[], int second[], int size) { int = 0; int * change = new int[2]; (i = 0; < size; i++) { if (first[i] != second[i]) { change[0] = first[i]; change[1] = second[i]; } break; } return change; } function main() { int mynumbers[] = {1, 0, 2, 3}; int possibilities[] = {0, 1, 2, 3}; int * change; change = getchange(possibilities, mynumbers, 4); printf("%i / %i\n", (change), (change+1)); } unfortunately function seems return addresses, not values... try change printf("%i / %i\n", (change), (change+1)); to printf("%i / %i\n", *(change), *(change+1)); in printf function need use int parameters, not int* . change variable pointer. must use *change and, using pointers arithmetics, *(change + 1) obviously, don't forget free allocated memory.

how can change verbosity level when running test monkey command line? these 2 commands work: adb shell monkey -p com.my.package 5000 adb shell monkey -p com.my.package -v 5000 the developer docs say, "each -v on command line increment verbosity level. level 0 (the default) provides little information beyond startup notification, test completion, , final results. level 1 provides more details test runs, such individual events being sent activities. level 2 provides more detailed setup information such activities selected or not selected testing." however, when try adb shell monkey -p com.my.package -v -v 5000 segmentation fault monkey -p com.my... . i tried adb shell monkey -p com.my.package -v 2 5000 , monkey reads 2 count, rather value -v . help? :) it should be: adb shell monkey -p com.my.package -vvv 5000

sqlite - Android: Knowing when all items in a database have their field set to the same value? -

i have app lets user select every item in list , set "favorite". thought neat if, when items set favorite, button switched "unselect all". the way i'm thinking doing registering contentobserver, whenever change made checked if items set favorite. realized may not efficient. can't think of other way, though, hints? how can know items in database have 1 of fields set same value (field favorite = 1, in case)? here solution should (i believe) "abort fast" if difference found. it avoids sorting/distinct phase select distinct or group by. approach may slower in situations and/or negligibly faster in others. sqlite darn fast! remember indexes play role in rdmbs performance . the inner select replaced literal value reduce complexity. in case, amusement. select exists (select * t val != (select val t limit 1))

matlab - Operation returns a scalar value when a vector of values is expected -

i'm evaluating simple function: y = (2*x)/sqrt( 1 + x.^2 ); where x vector 100 values in it. however, matlab makes y equal single scalar value in instance. if do: y = 2*x; i vector of values in y expected. if do: y = x.^2; i also vector of values in y expected. why above equation y = (2*x)/sqrt( 1 + x.^2 ); giving single value , not vector of values? the operation b/a (given b = 2*x , a = sqrt(1+x.^2) ) attempt perform matrix right division , row vector x solution in least squares sense system of equations ya = b , results in scalar value y . for element-wise array division , perform operation b./a instead (note . ).

Are idempotent functions the same as pure functions? -

-
i read wikipedia's explanation of idempotence. know means function's output determined it's input. remember heard similar concept: pure function. google them can't find difference... are equivalent? an idempotent function can cause idempotent side-effects. a pure function cannot. for example, function sets text of textbox idempotent (because multiple calls display same text), not pure. similarly, deleting record guid (not count) idempotent, because row stays deleted after subsequent calls. (additional calls nothing)

linq to sql concurrency issue! -

-
i have windows service deletes table rows. dont want delete rows , if rows loaded(to opertion) wcf service . seems should put locking mechanism , cant find on how . in regard ? thanks jamal. you shouldn't hold long term database locks. use kind of marking technique, such table of ids each loaded row foreign key original table. prevent deletions until wcf service deletes entries in auxiliary table. enable safe deletion appending where not exists (select * loaded_rows id = outer.id) delete statements. this model allows multiple "loaders", adding "loader_id" column auxiliary table. the main problem suggested approach wcf service must delete rows when it's done them. if neglects due bug or crash, rows permanently locked (or @ least until dba wanders by). there numerous ways work around this, revolving around kind of expiry mechanism.
