Which of the following statements is TRUE? Arrays are a higher-level, more convenient, abstraction than vectors. You must always use delete to deallocate stack variables, including simple ints. It is not possible to have a pointer to a function. The compiler does not catch vector bounds errors, where you access v[i] and i is greater than the size of the vector. QUESTION 2 If we execute the following code: queue > q q.push(10); q.push(20); q.pop(); q.push(30); q.push(40); q.pop(); int x=q front(); what is the value of x ? 10 40 20 30 If we execute the following code: stack s; s.push(10); s.push (20); s.pop(); s.push (30); s.push (40); s.pop(); int x=s.top(); what is the value of x ? 30201040 QUESTION 4 If you are using a library function that requires a char*, but you have a C++ string value stored in s, you can get the C string by casting s using static_cast char* >( s) calling tmpnam(s) charp;strcpy(p,s) calling s.c_str()
