c++ - How to get all ones or all zeros from boolean result? -

-

i (stupidly) thought if took boolean result of true, cast int , left-shifted end lsb repeated @ every bit, not!

if had boolean result , wanted convert ones true , zeros false, cheapest way (computationally) this?

bool result = x == y;  unsigned int x = 0;  //x becomes ones when result true //x becomes zeros when result false

like this, perhaps:

bool result = x == y;  unsigned int z = -result;

C# random value from dictionary and tuple -

-
i have following code, , need random item contains string "region_1" dictionary. public static dictionary<int, tuple<string, int, currencytype>> itemarray = new dictionary<int, tuple<string, int, currencytype>>() { { 0xb3e, new tuple<string, int, currencytype>("region_1", 1500, currencytype.fame) } }; public static int generateitemid(string shopid) { var generateditem = itemarray.elementat(new random().next(0, itemarray.count)).key; } how select this? it's not possible efficiently... first create static random @ class level... prevent non-random behaviour if run query on short period of time... (it's seeded discrete clock) static random rnd = new random(); then: var item = itemarray.values .where(t => t.item1 == shopid) .orderby(_ => rnd.next()) .firstordefault()
