Release Notes

LINQ for C++ (cpplinq) is an extensible C++11 library of higher-order functions for range manipulation. cpplinq draws inspiration from LINQ for C#.

This release includes just the source code.

What's new in this release:
  • join range operators: Inner Joins two ranges using a key selector
  • reverse range operator
  • distinct range operator
  • union_with range operator
  • intersect_with range operator
  • except range operator
  • concat range operator
  • sequence_equal range aggregator
  • to_lookup range aggregator

This is a sample on how to use cpplinq:
#include "cpplinq.hpp"

int computes_a_sum ()
{
    using namespace cpplinq;    
    int ints[] = {3,1,4,1,5,9,2,6,5,4};

    // Computes the sum of all even numbers in the sequence above
    return 
            from_array (ints)
        >>  where ([](int i) {return i%2 ==0;})     // Keep only even numbers
        >>  sum ()                                  // Sum remaining numbers
        ;
}
