C For Loop

[Paul Parkyn]

Hello all,
                I am trying to port a C program to Pascal but am not sure of 
the outcome of a For Loop e.g. 

         for( i = 4; i ; i--)  { do something}

        Could someone explain the effect of the middle i. I understand the 
middle i is used for a test e.g. i > 2
         Just how many iterations of the loop will take place before the test 
of i will terminate the loop. 


Best regards,
