Why this code prints "Hello" 4 times ?

Question

#include <iostream>
using namespace std;

int main()
{
int i;
for(i==1;i<=3;i++)
{
cout<<"Hello"<<endl;
}
return 0;
}

/* I know how to print hello 3 times.
But I just want to know why the above one prints "Hello" 4 times ??? */

Answer 1

because of i==1

so it takes i=0 by default
