If variable equal to 0 - c++

Question

Then it will reset to the questions number 1.
I wanted to implement health points system in my code, so that if your hp goes to 0 (zero) when choosing the wrong answer, it will start to question number 1
I'm new to c++ and doesn't know much about it but if you have any recommendation how to improve my coding i'm happy to take your advice.
Code:
void questions()
{
int score, end, hp = 1;
char ans[28];
cout <<"\t\tHEALTH POINTS= " << hp <<"\n\n";
cout << "1.What thing has to be broken before it can be used?\n\n"; //Questions
cout << "[A]-Egg,";
cout << " [B]-Heart,"; //Choices
cout << " [C]-Cube,";
cout << " [D]-Case";
cout << "\n\n";
cout << "YOUR ANSWER IS: ";
cin >> ans[1];
if (ans[1]=='a'||ans[1]=='A') //This will decide if the input is correct
{
cout << "YOUR ANSWER IS CORRECT: [A] - Egg \n\n";
score++;
}
else
{
cout <<"\nWRONG! ";
cout <<"YOU NOW HAVE "<< (hp=(hp-1)) <<" HP LEFT\n\n";
}
cout << "2.Jimmy's mother had three children. The first was called April, \nthe second was called May. What was the name of the third?\n";
cout << "[A]-May,";
cout << " [B]-Jimmy,";
cout << " [C]-April,";
cout << " [D]-Third";
cout << "\n\n";
cout << "Your Answer is: ";
cin >> ans[2];
if (ans[2]=='b'||ans[2]=='B')
{
cout << "YOUR ANSWER IS CORRECT: [B] - Jimmy \n\n";
score++;
}
else
{
cout <<"\nWRONG! ";
cout <<"YOU NOW HAVE "<< (hp=(hp-1)) <<" HP LEFT\n\n";
}
cout << "\n\t\t YOUR SCORE IS:" << score << "/2, ";
cout <<"YOU HAVE "<< hp <<" HP LEFT\n\n";
cout << endl;
cout <<"\n\t\t PRESS ANY KEY TO GO BACK TO CHOICES...";
getch(); //Holds the screen
system("cls");
questions();

Answer 1

One way to improve your approach might be implementing some sort of function to handle asking a question, with predefined choices, and getting an answer back. Instead of writing the code out twice like you do above to ask two questions, you could call the same function twice, passing in the different arguments.
