Answer 1

There is a simpler way of doing this:

#include <iostream>
#include <vector>

using namespace std;

int main() {
int in;
vector<int> vec;

while (cin >> in)
vec.push_back(in);

//now, you can access them like an array:

cout << vec[0] << endl;
cout << vec[1] << endl;

//to avoid getting an error because you’re trying to access an index larger than the vector:

cout << vec.size();
//returns # of elements.
}

Answer 2

nice, but the thing is that i don't reach at vector yet....

Answer 3

u should use java code instead of c++
