V533. It is possible that a wrong variable is incremented inside the 'for' operator. Consider inspecting 'X'.

The analyzer detected a potential error: a variable referring to an outer loop and located inside the 'for' operator is incremented.

This is the simplest form of this error:

for (size_t i = 0; i != 5; i++)
  for (size_t j = 0; j != 5; i++)
    A[i][j] = 0;

It is the 'i' variable which is incremented instead of 'j' in the inner loop. Such an error might be not so visible in a real application. This is the correct code:

for (size_t i = 0; i != 5; i++)
  for (size_t j = 0; j != 5; j++)
    A[i][j] = 0;

This diagnostic is classified as:

CWE-691 CERT-MSC01-C
