c - Regarding scanf and many values to input -

-

so i'm trying solve http://www.codeabbey.com/index/task_view/sum-in-loop , have 45 random numbers input. i'm coding using c want use scanf function. problem since it's 45 numbers (which separated spaces) want copy paste values program can solve them array. should this:

int x [45]; scanf("%d %d....(x42) %d",&x,&x,...(x42),&x);

or there more efficient way of doing this? (i hope there t_t)

you need not (and should not) write single format string containing 45(or whatever) format specifier, following 45 pointers.

you need use loop.

example:

  • for loop array, hold supplied operands, too

    int x[45] = {0}; int sum = 0; (int = 0; < 45; i++)    //style supported on c99 {    scanf("%d", &x[i]);    sum += x[i];  } printf("sum = %d\n", sum);

  • for loop without array, won't hold operands, result

    int x = 0; int sum = 0; (int = 0; < 45; i++)    //style supported on c99 {     scanf("%d", &x);     sum += x;  } printf("sum = %d\n", sum);

c# - TransactionScope not rolling back although no complete() is called -

i'm using transactionscope rollback transaction fail bool errorreported = false; action<importerrorlog> newerrorcallback = e => { errorreported = true; errorcallback(e); }; using (var transaction = new transactionscope()) { foreach (importtaskdefinition task in taskdefinition) { loader.load(streamfile, newerrorcallback, task.destinationtable, processingtaskid); } if (!errorreported) transaction.complete(); } i'm sure there no transactionscope started ahead or after code. i'm using entity framework insert in db. regardless state of errorreported transaction never rolled in case of error. what missing ? transactionscope sets transaction.current . that's does. wants transacted must @ property. i believe ef each time connection opened reason. probably, connection open when scope installed. open connection inside of scope or enlist manually. ef has nasty "design decision": default opens
