C++ std::uniform_real_distribution reset()用法及代码示例

// C++ code to demonstrate 
// the working of reset() function 
  
#include <iostream> 
  
// for uniform_real_distribution function 
#include <random> 
  
using namespace std; 
  
int main() 
{ 
    double a = 10, b = 20.5; 
  
    default_random_engine generator; 
  
    // Initializing of uniform_real_distribution class 
    uniform_real_distribution<double> distribution(a, b); 
  
    cout << "Next value in uniform_int_distribution:"
         << distribution(generator) << endl; 
    cout << "Next value in uniform_int_distribution:"
         << distribution(generator) << endl; 
    cout << "Next value in uniform_int_distribution:"
         << distribution(generator) << endl; 
  
    // Using reset() 
    distribution.reset(); 
    cout << endl 
         << "uniform_int_distribution has been reset."
         << endl 
         << endl; 
  
    // Now the next value won't be in the previous progression 
    // and will be another progression 
    cout << "Now next value in uniform_int_distribution:"
         << distribution(generator) << endl; 
  
    return 0; 
}
