For each program: show a hand trace of the code; determine the output and explain, briefly, what the code accomplishes. #include using namespace std; bool isAthing(int>; int countAthing(int &, int); void doIt(int); int main() {doIt(12); doIt(17); doIt(144);} void doIt(int num0) {int numl = num0; bool first-true; for l;i++} {if (isAthing (i) && numl % i == 0) {if (!first) cout using namespace std; int doIt(int); int main () {cout 0) {num1 + = num2+ (num0%2); num0/= 2; num2 * = 10;} return num1;}
