The template function calls operator() of Gen repeatedly and packs the returned values into a floating-point value x of type RealType until it has gathered the specified number of mantissa bits in x. The specif
} 以上代码里的random_shuffle使用随机种子,不写第三个参数。 下面一个例子,使用自定义的随机种子myrandom //random generator function:intmyrandom (inti) {returnstd::rand()%i; }std::vector<int>myvector;//set some values:for(inti=1; i<10; ++i) myvector.push_back(i);//1 2 3 4 5 6 7...

The random_shuffle() function sorts the elements in a data range randomly.The range of data is specified by iterators.Note: The example above is likely to always sort the elements in the same way. In order to change the random sorting you can use the srand() function to seed the random...

There are many options to choose from in the <random> header, and any of them is preferable to the outdated C Runtime function rand(). For information about what's wrong with rand() and how <random> addresses these shortcomings, see this video. Examples The following code...
