6. for (i = 0; i < 1024; i++) C[i] = A[i]*B[i]; for (i = 0; i < 1024; i+=4) C[i:i+3] = A[i:i+3]*B[i:i+3]; #pragma loop(hint_parallel ( N ) ) for (i = 0; i < 1024; i++) C[i] = A[i]*B[i]; N is the number of cores you want to parallelize over

10. #include using namespace concurrency; void AddArrays(int n, int * pA, int * pB, int * pC) { array_view a(n, pA); array_view b(n, pB); array_view sum(n, pC); parallel_for_each( sum.extent, [=](index i) restrict(amp) { sum[i] = a[i] + b[i]; } ); } void AddArrays(int n, int * pA, int * pB, int * pC) { for (int i=0; i<n; i++) { pC[i] = pA[i] + pB[i]; } portable view that works like an N-dimensional “iterator range” tells the compiler to check that this code can execute on Direct3D hardware execute the lambda on the accelerator once per thread

13. circle* p = new circle( 42 ); vector vw = load_shapes(); for( vector ::iterator i = vw.begin(); i != vw.end(); ++i ) { if( *i && **i == *p ) cout << **i << “ is a match\n”; } for( vector ::iterator i = vw.begin(); i != vw.end(); ++i ) { delete *i; } delete p; auto p = make_shared ( 42 ); vector > vw = load_shapes(); for_each( begin(vw), end(vw), [&]( shared_ptr & s ) { if( s && *s == *p ) cout << *s << “ is a match\n”; } ); Then Now new  make_shared T*  shared_ptr no need for “delete” automatic lifetime management exception-safe for/while/do  std:: algorithms [&] lambda functions auto type deduction not exception-safe missing try/catch, __try/__finally
