Analyse the following code snippet and choose the answer:-
#include Class Temp
{
private:
int m_ival;
public:
Temp()
{
Cout<<"OBJECT CREATED\n"< }
~Temp()
{
Cout<<"OBJECT DESTROYED\n"< }
};
void fnRead()
{
Temp oTempObj;
}
int main()
{
fnRead();
cout<<"IN MAIN \n"< return 0;
}
OBJECT CREATED OBJECT DESTROYED
OBJECT CREATED OBJECT DESTROYED IN MAIN
OBJECT CREATED IN MAIN
Compilation Error

Observe the following code and chose the correct statement(s)
class Name
{
const char *s ; .
};
class Table
{
Name *p; size_t sz ; public :
Table(size_ts = 15) {p = new Name [sz = s]; }
~Table() {delete [ ]p ;}
Name * lookup(const char *);
bool insert(Name *);
};
