Programming Quiz #3

This one is pretty tricky. The programmer expected the code below to parse out the words of each semi-colon seperated line. However, it doesn't seem to process anything past the first semi-colon. What's wrong? void process(char *str) { char *ptr; ptr = strtok(str, " "); printf("Some words: "); while (ptr) { printf("%s ", ptr); ptr = strtok(NULL, " "); } printf("\n"); } int main(void) { char *ptr; char buf[80]; fgets(buf, 80, stdin); ptr = strtok(buf, ";"); while (ptr) { process(ptr); ptr = strtok(NULL, ";"); } }

Answer to quiz #2: Think about the order in which constructors are run. Passing a pointer to a member to the base class constructor is risky because the constructor for the member hasn't been run yet.
