Constant variable multiplied with user input - c++

Question

I've been trying to create a simple program that allows me to display a total score after the user has entered the ammount of successful hits, totalHits, by multiplying that input with the constant variable POINTS resulting in another variable; score.
I didn't think creating such a program would be any problem, but as usual, I was wrong.. When I run the program score is always random, even if I enter '1' as totalHits every time. It can differ from 444949349 to -11189181 to name a couple of examples. I have no idea what I've done wrong, so it would be great if someone could give me a clue as to what to do next :)
Here's the code:
#include <iostream>
using namespace std;
int main()
{
const int POINTS = 50;
int totalHits;
int score = totalHits * POINTS;
cout << "Please enter the ammount of successful hits: ";
cin >> totalHits;
cout << "You hit " << totalHits << " targets, and your ";
cout << "score is " << score << " ." << endl;
cin.ignore(cin.rdbuf()->in_avail() + 2);
return 0;
}
Big thanks to KerrekSB and Paddyd for providing me with the correct answer. Here's the finished code with comments:
#include <iostream>
using namespace std;
int main()
{
const int POINTS = 50;
int totalHits;
cout << "Please enter the ammount of successful hits: ";
cin >> totalHits;
cout << "You hit " << totalHits << " targets, and your ";
/*As you can see I moved the line below from the top of the code.
The problem was I had not properly learned how C++ executes the code.
The orignal code was written in a way that calculates `score` before
the user could decide it's value, resulting in a different total score than
it should have been. In the finished code, the user inputs what
value `totalHits` is, THEN score is calculated by using that value. */
int score = totalHits * POINTS;
cout << "score is " << score << " ." << endl;
cin.ignore(cin.rdbuf()->in_avail() + 2);
return 0;
}

Answer 1

int totalHits;
int score = totalHits * POINTS;
You are multiplying by an uninitialized variable (totalHits)! You need to apply a value to totalHits before doing this calculation.
Try using the code like this:
const int POINTS = 50;
int totalHits;
int score;
cout << "Please enter the ammount of successful hits: ";
cin >> totalHits;
cout << "You hit " << totalHits << " targets, and your ";
score = totalHits * POINTS; //totalHits has a value here
cout << "score is " << score << " ." << endl;
cin.ignore(cin.rdbuf()->in_avail() + 2);
return 0;
