I've seen many people use if once again after if, for eg:

pawn Код:

if(blah == 6)
{
    //..........
}
if(blah == 7)
{
   //sssssss
}

But I thought it was like this:

pawn Код:

if(blah == 6)
{
    //..........
}
else if(blah == 7)
{
   //sssssss
}

What is the difference between these two, please if someone would explain.
