c++ - Initilization of a wchar_t array with wmemset. Does encoding matter? -


how correctly initialize wchar_t array wmemset? should use '\0' or l'\0' ? matter? encoding matter ? (unicode, iso####)

eg

wchar_t arr[20]; wmemset(arr, '\0', sizeof(arr));

thank you. (sorry if have made big mistake)

you need use l'' form wchar_t type, although value fits within char (such '\0') automatically converted using usual integer promotions. see character literal or c++ character literals.

it's unclear me code page source interpreted in. safe, it's best use l'\u20ac' or l'\u000020ac' form specify characters outside of ascii character set.

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.
