in event need generate probability, example bias coin 75% of tossing head , 25% tossing tail. conventionally, way: #include <cstdlib> #include <iostream> #include <ctime> using namespace std; int main() { int heads=0, tails=0; srand(time(null)); number = rand() % 100 + 1; //generate random number 1 100 if (number <= 75) //75% chance heads++; //this head else tails++; //this tail } this working code, when answered similar question on bias coin in user, of users mentioned multiple of 100. since random function generates uniform distribution, feels above code enough simulating probability event. in past posts, user bathsheba mentioned somehting multiples of 100: program simulates coin toss bias coin wanted know possible problems in code in relation that. my question is: above code acceptable code create simulation probability? or there flaws in these codes affect accuracy of simulated res...

we have several sql servers set in workplace linked each other , make use of 4-part db names in lot of our code. considering moving of our databases 1 server , assessing impact on our code, no 1 here seems know beyond linked server name protocol used in [server] portion of 4pt db name [server].[database].[dbo].[table] . [server] portion wins entry, dns, or sql server doing clever on it's own there? if it's dns, simple enough move db's (minimal code changes), else , may have reconsider our strategy. server symbolic name, datasrc matters. suppose have linked server created this: exec master.dbo.sp_addlinkedserver @server = n'test', @srvproduct=n'', @provider=n'sqlncli', @datasrc=n'server2008r2' and queries select test.database.schema.table . recreate linked server different @datasrc , still work, time read data different physical server (as long data there , security set right).
