What will be the output of the following C++ code?
#include <iostream>
#include <algorithm>
#include <vector>
using namespace std;
bool myfunction (int i, int j)
{
return (i==j);
}
int main ()
{
int myints[] = {10, 20, 20, 20, 30, 30, 20, 20, 10};
vector<int> myvector (myints, myints + 9);
vector<int> :: iterator it;
it = unique (myvector.begin(), myvector.end());
myvector.resize( distance(myvector.begin(), it) );
unique (myvector.begin(), myvector.end(), myfunction);
for (it = myvector.begin(); it != myvector.end(); ++it)
cout << ' ' << *it;
return 0;
}

What is the difference between '++i' and 'i++' in C++?
A. None of the above
B. They both have the same effect
C. '++i' increments the value of 'i' before returning it, while 'i++' increments the value of 'i' after returning it
D. '++i' increments the value of 'i' after returning it, while 'i++' increments the value of 'i' before returning it
