![]() ![]() I tested msvc110 as well, and the results were similar to msvc100. However, my experience is that GCC does not optimise very well on Windows. For GCC on Windows, memcpy and copy were slightly slower than the constructors and assign, although the difference was smaller. I tested at 64-bit Linux as well, with the following outcome for Clang 3.2 constructor (1): 530000 Press Ctrl+D to fill (Down) The keys pressed are always the same, so you can put this on a keyboard macro. Press Ctrl+Shift+Up to select up to the cell with the fill value. Press Right to get back to the column that will be populated. Of course the exact numbers and ratios depend on the vector size, but the conclusion for msvc100 is obvious: as suggested by Rapptz, use std::copy.Įdit: the conclusion is not obvious for other compilers. Press Ctrl+Down to go to the end of the data. The results are quite clear: std::copy performs as well as std::memcpy, whereas both constructors and assign are an order of magnitude slower. If (diff != 0) cout << "one of the methods produces invalid copies" << endl Ĭout << "constructor (1): " << t_constructor1 << endl Ĭout << "constructor (2): " << t_constructor2 << endl Īt my PC, compiled for 圆4 with msvc100, fully optimised, this produces the following output: constructor (1): 22388 Uint8_t diff = (c_constructor1 - c_constructor2) + Verify that all copies are correct, but also prevent the compiler Uniform_int_distribution random_byte(0x00, 0xff) įor (size_t i = 0 i destination(source) įor (size_t i = 0 i destination(source.begin(), source.end()) ĭestination.assign(source.begin(), source.end()) įor (size_t i = 0 i destination(source.size()) Ĭopy(source.begin(), source.end(), destination.begin()) ![]() Using the container's method is generally more performant than using generic algorithms, so a combination of vector::resize() and std::copy() or even memmove()/memcpy() would be a work-around, if the vendor didn't optimize the container sufficiently.īased on the suggested solutions, I decided to put together a small benchmark. Take care, that otherVect has exactly the same element type (not e.g. Which uses the default allocator for newVect.Īnother possibility is std::vector newVect nevVect.assign(otherVect.begin(), otherVect.end()) Īll of them (including the copy constuctor when otherVect uses the default allocator) should boil down to a memmove/memcpy in a good STL implementation in this case. If you just want to copy the contents of otherVect, use std::vector newVect(otherVect.begin(), otherVect.end()) Range(FirstColumn & (i - 1)).Copy Range(FirstColumn & i) End. The otherVect's allocator object has to be copied (and used) as well, which needs more efforts to get it performant in the STL implementation. Paste the following code into the new function: FirstColumn InputBox('Please enter the column letter.') FirstRow InputBox('Please enter the row number.') LastRow Range(FirstColumn & '65536').End(xlUp).Row. If you use the copy constructor like in std::vector newVect(otherVect) Louis and how to reconstruct your records to support a VA disability compensation claim.This answer is not specific to the msvc100. Reconstruct military records destroyed in NPRC fireįind out if your records may have been destroyed in the 1973 fire at the National Personnel Records Center (NPRC) in St. Thats half the time of Amples first-gen station.
