c++ - How can I avoid std::vector<> to initialize all its elements? -

edit: edited both question , title more precise. considering following source code: #include <vector> struct xyz { xyz() { } // empty constructor, compiler doesn't care xyz(const xyz& o): v(o.v) { } xyz& operator=(const xyz& o) { v=o.v; return *this; } int v; // <will initialized int(), means 0 }; std::vector<xyz> test() { return std::vector<xyz>(1024); // memset() :-( } ...how can avoid memory allocated vector<> initialized copies of first element, o(n) operation i'd rather skip sake of speed, since default constructor nothing ? a g++ specific solution do, if no generic 1 exists (but couldn't find attribute that). edit : generated code follows (command line: arm-elf-g++-4.5 -o3 -s -fno-verbose-asm -o - test.cpp | arm-elf-c++filt | grep -ve '^[[:space:]]+[.@].*$' ) test(): mov r3, #0 stmfd sp!, {r4, lr} mov r4, r0 str r3, [r0, #0] str r3, [r0, #4] str r3, [r0, #8]
