Random Numbers in C++ #include <iostream> #include <ctime> #include <cstdlib> using namespace std; int main () { int i,j; // set the seed srand( (unsigned)time( NULL ) ); // generate 10 random numbers. for( i = 0; i < 10; i++ ) { // generate actual random number j ...
std::srand ( unsigned ( std::time(0) ) );//srand函数是随机数发生器的初始化函数。 //using built-in random generator: //std::random_shuffle ( myvector.begin(), myvector.end() ); //using myrandom: std::random_shuffle ( myvector.begin(), myvector.end(), myrandom); //print out...
Return pointer to random element in built-in array intarray [] = {1,2,3};autorandomPtr = Random::get( array ); Container of random values Return container filled with random numbers. Any containers with "begin", "end" and "insert" methods are applicable ...
While these are high quality random numbers and different every time this program is run, they are not necessarily in a useful range. To control the range, use a uniform distribution as shown in the following code:C++ نسخ #include <random> #include <iostream> using namespace std;...

Edit & run on cpp.sh Oct 29, 2012 at 7:52am brandonator(153) sorry read your code and becausse of the speed i thought it was 123123123, when in reality it was more random (put a pause at the end), anyways, can you explain why your way comes up with better random numbers (line...
