2) int countOccurrences(const vector & v, int k)

Implement the function countOccurrences whose declaration appears above. The first argument of the function is a vector v of integers and the second argument is an integer k. The function returns the number of times k occurs in v

Solution

template<typename T>
int countOccurrences(const vector<T> & v, int k)
{
   int count = 0;
   for (int i = 0; i < v.size(); i++)
   {
       if (v[i] == k)
           count++;
   }
   return count;
}
