cin is eating output stream

#include <iostream>

using namespace std;

void main(int argc, char* argv[])
{
    int conversion, hash;

    cout << "Select one." << endl;
    cout << "0: Radix Method 32" << endl;
    cout << "1: Radix Method 64" << endl;
    cout << "2: SumUp" << endl;
    cin >> conversion;

    cout << endl << "Select one." << endl;
    cout << "0: Division" << endl;
    cout << "1: Multiplication" << endl;
    cin >> hash;

    cout << "Conversion: " + conversion << endl;
    cout << "hash: " + hash << endl;
}

As simple as this is, I'm getting wild output. I feel like it's something obvious but I'm too tired to see it. The number I enter into the variables is the number of characters removed from the next output string. ex: 

Select one.
0: Radix Method 32
1: Radix Method 64
2: SumUp
1

Select one.
0: Division
1: Multiplication
2
onversion:
sh:
Press any key to continue . . .

Select one.
0: Radix Method 32
1: Radix Method 64
2: SumUp
5

Select one.
0: Division
1: Multiplication
1
rsion:
ash:
Press any key to continue . . .

Am I crazy or does this make no sense? Am I using cin wrong? I haven't used C++ for a few months, but I can't see anything wrong with it.

cout << "Conversion: " + conversion means to print from conversion elements after the head of the array.

You may want this (change + to <<):

cout << "Conversion: " << conversion << endl;
cout << "hash: " << hash << endl;
