### Vectors

Hello guys. I've a problem with vectors and I can't realise what's wrong. My task:
Enter 2 numbers N and M. N shows what is your length of your vector and M shows which number you're looking in vector. I need to find how many times my number duplicates in vector and print it.
I have to use find & vectors.

 ``1234567891011121314151617181920212223`` `````` #include #include #include using namespace std; int main() { vector myVector; vector::iterator it; int n, m, E, F(0); cin >> n >> m; for (unsigned i = 0; i < n; i++) { cin >> E; myVector.push_back(E); } for (unsigned i = 0; i < n; i++) { it=find(myVector.begin(), myVector.end(), m); if (it != myVector.end()) { F++; } else F = 0; } cout << F << endl; return 0;``````

You have a couple of problems.

1) Line 16: As you iterate through the vector at line 15, you're always starting the find at the beginning of the vector.. Therefore, you will always find the first m. Use begin()+i to start at the i'th element.

2) Line 20: You don't want to set F back to 0 here. Consider if the first iteration found a match, then on the next iteration you do not find a match. You still want F to reflect the count of duplicates.
