What’s wrong with this code?[2007-02-26 23:42:22]   
Assuming the function lookupName is defined, what’s wrong with this code (hint: 2 bugs)?

const char *getName(const char *c) {
std::string name = lookupName(c);
if (name == NULL)
return "Anonymous";
return name.c_str();
}

int main(int argc, char *argv[]) {
const char *name = NULL, *c = NULL;
if (argc >= 2)
c = argv[1];
name = getName(c);

printf("My name is %s ", name);
return 0;
}

Find missing number[2007-02-26 23:42:18]   
Given a consecutive list of numbers from a to b, one number is removed.
The list is then scrambled. Find the missing number.
int find(int a, int b, int *array);
hint: sum(1 to n) is n(n+1)/2
using the same logic, sum(a to b) is (b-a)/2 * (b+a)
