Most such loops iterate over 0..N-1 inclusive, so would need "<". So, in

the loop enter with i=0
than make i= 1..N N in the count
so would be N+1 times iterations
that are 0..N or 0,1,2,3...,N
 
<= is not a Typo
 
i not find the problem

Is there still no problem? Except this will be in the middle of 1000
lines of busy code with longer identifiers and more elaborate expressions.

in this case the if the lenght of A is N, the loop has to be

for(i=0; i<N; ++i) A[i] = i;

so i is in the range 0..N-1
but i never use macro/enum as lengh of arrays, or at last don't
rememeber i have had used that
