how about this ?

#include <iostream>
#include <cstdlib>
#include <string>
#include <vector>
using namespace std;

int main()
{
    int n;

    cout << "Masukan Jumlah Wahana : "; cin >> n;

    vector<string> wahana;
    vector<int> tiket;

    string temp;
    int tmp2;
    for (int i = 0; i<n; ++i)
    {
        cout << "Nama Wahana " << i << " : " <<flush; cin >> temp;
        wahana.push_back(temp);
        cout << "Jumlah tiket Wahana " << i << " : " <<flush; cin >> tmp2;
        tiket.push_back(tmp2);
    }


    return 0;

}
