Estimating probability of a score (Pig) C++ -


(i'm using c++, sorry!)

i need simulate single turn of game of pig. user defines "hold" value, , dice rolled until value met/passed, or until 1 rolled, sets score 0 , ends turn.

there value, turnnum, if will, decide how many times turn simulated holdnum.

where i'm running wall needs output score of each attempt, estimated probability, probability adding 1.000000 (100%).

for example: if hold value 21, , number of times ran turn simulation 4, results may like:

score/estimated probability:

0/.500000

21/.250000

22/.250000

23/.000000

24/.000000

25/.000000

26/.000000

which mean our simulation hit 0 twice, 21 once, , 22 once.

i have of code need (the singleturn function, function simulates dice), have no idea how make "remember" every time got specific score can incremented can divide number of turn simulations number probability.

not asking code written me, poke in right direction. can post other functions if necessary.

depending on language answer vary. i'll assume you're using c++ or java or similar language has needed types.

option a

generally in case use dynamic array store of scores, can go through array , tally need @ end.

to make super easy use standard sort routine , sort array according size, can number of each of values.

option b

another solution use map or dictionary type maps particular value value, in case map score count increment each time score.

something (c++)

map<int,int> mymap; //creating std::map mymap[thescore]++; //incrementing score variable

you have tons of different options!

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.

php - Nothing but 'run(); ' when browsing to my local project, how do I fix this? -

i added new project. made mistake in projectname.conf file in sites-available apache2, led me reinstalling apache2. after reinstalling , re-enabling projects on every page of every project .. <body> run(); </body> .. i've run composer update, restarted service, restarted pc, checked config files, tried disabling new project. there nothing in error log, , access.log: 127.0.0.1 - - [15/may/2015:01:40:47 +0200] "get / http/1.1" 304 181 "-" "mozilla/5.0 (x11; ubuntu; linux x86_64; rv:38.0) gecko/20100101 firefox/38.0" maybe i'm forgetting apache2 reinstall? don't think did different last time installed it. looks haven't setup php correctly. take @ this great guide , maybe you're forgetting link php config apache2.
