Question
See the code below. Write a template based implementation of function my_count which counts the
number of instances of the first element in a sequence. For example, if the input is “1 3 2 4 3 1 4 1”, the
output is “Found 3 instances of target 1”. Hint: Seek inspiration from the STL_intro_handout.
#include <iostream>
#include <list>
using namespace std;
int main() {
list<int> v;
list<int>::iterator iv;
int value;
while (cin >> value)
v.push_back(value);
int target = *v.begin();
int N = my_count(v.begin(), v.end(), target);
cout << "Found " << N << " instances of " << target << "\n";
}
