this question has answer here: square of number being defined using #define 11 answers #include <stdio.h> #define abs(x) x > 0 ? x : -x int main(void) { printf("%d\n", abs(abs(3 - 5))); return 0; } why program above output 8 , not 2 while program below outputs 2? #include <stdio.h> int abs(int x) { return x > 0 ? x : -x; } int main(void) { printf("%d\n", abs(abs(3 - 5))); return 0; } short answer "because macro not function". long answer macro parameters expanded text of program, c compiler sees long expression: 3 - 5 > 0 ? 3 - 5 : -3 - 5 > 0 ? 3 - 5 > 0 ? 3 - 5 : -3 - 5 : -3 - 5 > 0 ? 3 - 5 : -3 - 5 in expansion, negative sign applies 3 , not (3-5) , yielding negative 8. although can work around issue placing parentheses around x in macro definition, defining inline functi...

really hard explain easy question : i want b46 contain same value, if rows added or removed i'm sure there's easy script input given value on edit i'm not sure write thank in advance help! here sample. each time sheet edit, script set value on b46: function onedit(e){ var value = /* value here */ ; var sheet = spreadsheetapp.getactivespreadsheet().getactivesheet(); sheet.getrange("b46").setvalue(value); } beware: script not modify rest of sheet remove old values. example: if add row above row 46, script put value on new b46 cell, not delete old one.

i trying thought pretty straightforward thing, having issue. have code in .net application insert new record table using sqlcommand. i passing in either datetime value or null. code below doesn't seem work though: command.parameters.addwithvalue("@settledate", iif(string.isnullorempty(settledate), nothing, datetime.parse(settledate))) where "settledate" string containing date null. think code cover condition of not attempting parse null value, when ran following error looks datetime.parse method: string reference not set instance of string. parameter name: s how be? if "settledate" null should never reach parse method. you should use short circuit opertator of vb.net dbnull.value if(string.isnullorempty(settledate), dbnull.value, datetime.parse(settledate))) the if operator , contrary iif function doesn't try evaluate both sides of expression if first 1 true. note pass null value sqlparameter use dbnull.value .

i looking alternative api-chaining work in apigee older version. migrating api-proxies apigee cloud apigee older version, stuck in migration api-chaining not working in apigee. as creator of api chaining, can apigee cannot it. the reason being api chaining(tm) relies on new api pattern abstracts communication layer business logic solving architectural cross cutting concern caused old api pattern in distributed architectures. api chaining intended 1 can chain multiple api calls using 1 request/response unless abstract communication layer, backend still have redirect handle each separate api call creating separate request/response each call. you can see more on following videos springone conference videos: https://www.infoq.com/profile/owen-rubel
