C++ Builder Помогите решить задачу плиз

#include <iostream>
using namespace std;
void work(short *, const size_t);
void show(short *, const size_t);
int main() {
    size_t size;

    short a[] = { 1, 0, 3, 0, 7 };
    size = sizeof(a) / sizeof(short);
    show(a, size);
    work(a, size);

    short b[] = { 1, 2, 3, 4, 5, 6 };
    size = sizeof(b) / sizeof(short);
    show(b, size);
    work(b, size);

    short c[] = { 1, 2, 3, 0, 5, 7, 8 };
    size = sizeof(c) / sizeof(short);
    show(c, size);
    work(c, size);

    cin.get();
    return 0;
}
void show(short * _v, const size_t _sz) {
    for (unsigned n = 0; n < _sz; n++) cout << ' ' << _v[n];
    cout << endl;
}
void work(short * _v, const size_t _sz) {
    bool beg = false, end = false;
    unsigned bg = -1, ed = -1;
    for (unsigned n = 0, m = _sz - 1; n <= m; n++, m--) {
        if (!beg && !_v[n]) {
            beg = true;
            bg = n;
            ++bg;
        }
        if (!end && !_v[m]) {
            end = true;
            ed = m;
            ++ed;
        }
        if (beg && end) break;
    }
    if (beg && end) cout << " first: " << bg << endl << " second: " << ed;
    else if (beg) cout << " first: " << bg << endl << " second: " << bg;
    else if (end) cout << " first: " << ed << endl << " second: " << ed;
    else cout << " Not zero!";
    cout << endl << endl;
}

С С++ не очень знаком, на C# пишу, но код будет как-то так выглядеть:

int mas[] = {/* Массив */};
int FirstNull = 0;
int LastNull = 0;
boolean Check = false;
for (int j = 0; j < mas.Length; j++){
if (mas[j] == 0){
LastNull = j;
if (Check == false){
FirstNull = j;
Check = true;
}
}
}
cout >> "Первый нуль в позиции: " >> FirstNull >> endl >> "Последний нуль в позиции: " >> LastNull >> endl;
