this question has answer here: why cout print char arrays differently other arrays? 4 answers int main () { int intarr [5] = {1,6,7,9,3); char charr [7] = "avneet"; std::cout << intarr << "\n"; std::cout << charr << "\n"; return 0; } the first line program prints memory address , second line, whole string (avneet). what's making difference? 1 more question. in int case, address what? address of entire array or address of first element of array. std::basic_ostream<> has overloads of operator<< char const* , signed/unsigned versions expect c-style zero-terminated string. and void const* overload used other pointer types , outputs address.

i'm planning use stm32 board send can frames. implemented simple scheduler contains 10 tasks;one task responsible send frames. to job declared structure can frame: typedef struct { unsigned int id; unsigned char data[]; unsigned char dlc; unsigned int timeofsend //this time in ms in frame should sent }tframe; and declared table of frames sent aubframes[max_frames] = { {0x12, 0xaabbcc, 4, 100}, {0x12, 0xaabbcc, 4, 1000}, {0x12, 0xaabbcc, 4, 2000}, {0x12, 0xaabbcc, 4, 2010} }; this tell board send first frame after 100 ms, second after 1000 ms, etc. what do: i added new task in scheduler period of 10 ms. task check aubframes table , if it's time send frame sends concerned frame, else nothing done. problem solution there big loss of time. example, send first frame scheduler access task 9 times, nothing do. is there solution scheduling more effective? i thought use timer interrupt, don't think that's solution since th...
