What responsibilities are to comply C\C++ standard? -


little bit stupid question. example i've read, in c11 added support of threads. then, example gcc compiler stm32f4 said, supports c11 standard. so, mean now, without os i'll achieve threading support??? how can be?

another example - g++ stm32 supports std::vectors, , works,even without os's memory management. mean memory manager inside compiler? or not?

so, mean now, without os i'll achieve threading support???

it means language specified multi-threaded programs can written correctly, well-defined synchronisation when accessing shared data; , full hosted implementation should provide thread library. doesn't mean implementations allow multiple threads: depend on support underlying system.

this mean memory manager inside compiler?

yes, typically language run-time includes heap manager. assigned memory (either obtained os, or allocated in other system-dependent manner, perhaps static block when program starts), splits smaller lumps support dynamic allocation within program.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
