This code has missed semicolon (in 'int amount =' line), but IDE highlights this code as wrong:

#include <iostream>

using namespace std;

int readNumberOf(const char* item, int min, int max) {
    cout << "Enter number of " << item << " (" << min << " <= N <= " << max << "): ";

    string s;
    getline(cin, s);
    int amount = strtol(s.c_str(), 0, 10)

    cout << endl;

    if (amount < min) {
        cout << "number of " << item << " cannot be less than " << min << '.' << endl;
        cout << min << " item is taken" << endl << endl;

        amount = min;
    } else if (amount > max) {
        cout << "number of " << item << " cannot be more than " << max << '.' << endl;
        cout << max << " items is taken" << endl << endl;

        amount = max;
    }

    return amount;
}
