#include <iostream>
using namespace std;

int main()
{
int age;
cin>>age;
if (age>18)
{cout .....}
if (age==18)

Answer 4

#include <iostream>
using namespace std;

int main()
{
int age;
cout<<"This person is ";
cin>>age; {
if (age >0) {
if(age >= 18) {if (age < 130)
{
cout << "an Adult"; }
else { if (age>=130)
{if (age<2000)
cout<< "a vampire!!";} }}
else {if (age<18){if (age>12)
{cout << "a Teenager";
}}}
}
if (age<=12) {
cout << "a Child";
}

else {if (age>=2000)
cout << "yo mama!!";
}
}
return 0;
}
finally running code!! most error were bcoz of extra } at end of program
