What will be the output of the following C++ code?

#include <iostream>
#include <string>
using namespace std;
int main ()
{
    string str ("Steve jobs");
    unsigned long int found = str.find_first_of("aeiou");
    while (found != string :: npos)
    {
        str[found] = '*';
        found = str.find_first_of("aeiou", found + 1);
    }
    cout << str << '\n';
    return 0;
}
