Samples

Here is a sample Python code, producing infinite list of Fibonacchi numbers and corresponding C++ code with pseudo-generator:

def fibonacchi():
    "Generator, yielding infinite list of fibonacchi numbers"
    f0 = 1
    f1 = 1
    while True:
         yield f0
         f0, f1 = f1, f0+f1

#Sample usage of the above generator:
#Printing all fibonacchi numbers below 1000
for f in fibonacchi():
     print f
     if f > 1000:
         break

C++ analog with pseudo_generator

#include "pseudo_generator.hpp"
struct fibonacchi: generator< int >

{

    int f0, f1;

    int operator()();

}
int fibonacchi::operator()()

{

    DECLARE_GEN1( state1 );

    f0 = 1;

    f1 = 1;

    while( true ){

        YIELD;

        int f2 = f0 + f1;

        f0 = f1;

        f1 = f2;

    }

    END_GENERATOR;

    return -1; //Dummy return to suppress warning.

}
//Sample usage

int main( int argc, char* argv[] )

{

    using namespace std;

    fibonacchi gen;

    for( int x; gen >> x; ){

        cout << x << endl;

        if ( x > 1000 )

              break;

    }

    return 0;

}
