can explain me why output follows? why loop runs second time after (int i) gets value 9, not less 5? it seems if (int i) greater 5 still adds 3 body won't run second time. why? #include <iostream> using namespace std; int i=0; int main() { for(;i<5;i+=3){ i=i*i; } cout << << endl; //output: 12(i) it works way, more or less: i = 0 < 5 ? yes, keep on i*i = 0 i+=3 => ==3 < 5 ? yes, keep on i*i = 9 i+=3 => 12 < 5 ? no, exit loop you write for(initialization; condition; excuteattheendofcycle) : initialization executed once @ beginning, condition evaluated before each cycle, excuteattheendofcycle ( i+=3 , in case), it's executed @ end of each cycle, before further evaluation of condition

why there different stack variables if declare them in global or function scope? 1 of 2 example crashes, because of stack overflow. one, define variable inside scope. does crash: constexpr size_t max = 1000000; // customise int main() { int arr[max]; return arr[max - 1]; } does not crash: constexpr size_t max = 1000000; // customise int arr[max]; int main() { return arr[max - 1]; } info: cygwin, gcc 4.9 edit: know, second example have memory in data segment. how big can data segment be? big heap area? the first 1 constexpr size_t max = 1000000; // customise int main() { int arr[max]; return arr[max - 1]; } you declare array in function, goes stack limited , cause stack overflow. the second 1 constexpr size_t max = 1000000; // customise int arr[max]; int main() { return arr[max - 1]; } you declare @ global, should accesible between function goes heap (rather big). not using stack here. source : static , global variable in memo...
