This time we have a real problem. We are using the variable
|
||
|
|
'i' in the main loop to count and again in the function.
|
||
|
|
|
||
|
|
Thus the function will change the value seen by the 'main'
|
||
|
|
routine - and will cause *Serious* problems

This function returns the sum of the number 0 -> i, but
|
||
|
|
summing from the limit back to zero ( to prove a point ! )
|
||
|
|
|
||
|
|
The problem this will cause is that at the end of the routine
|
||
|
|
the value of 'i' will always be '1' which will stop the loop
|
||
|
|
in 'main' working !
