That's supposed to be a correct and well-known code to arrange integers from inferior to superior but compiler still insists saying "illegal assignment to for loop 'j' variable".
What's the problem?
The problem is here:
You are not allowed to assign to the
for
loop variable.Perhaps you meant to write
