fun situations can arise when you write , instead of ; For those not in the know, in c++ the comma operator evaluates the left expression, discards the value, then evaluates the right expression and returns the value. if you now have a a situation like this

int i = 0,
printf("some message");

i has a completely different value, since it actually uses the return value of printf instead

Easy solution:

Find all: ;

Replace with: ,
