Why this code is not giving error?

Why this code is not giving error? We cannot declare the same variable twice but here when the inner loop terminates and re-enters every time i is re-declared. ??Why is it not giving error??

  #include<iostream>
using namespace std;
int main()
{
for(int j=5;j>0;j--)
{
    for(int i=1;i<=5;i++)
    {
    }
}
    cout<<"hello";
    return 0;
}

how does it ever get to the i loop? j start out > 0 therefore the outer loop should never execute.

but if it did... i is able to re-declare itself because its scope is limited to the for loop. once the loop finishes, it is destroyed, and thus can be redeclared when the loop starts again.
