address of array at index
|
| |
hello group,
i use the function std::inner_product(&arya[0], &arya[4], &aryb[0], 0.0f) with the c-style and/or c++11-style array. does the compiler set the addresses at compile time or is there a runtime overhead to get the addresses of array indices?
thanks & cheers, chris
