V3014. It is likely that a wrong variable is being incremented inside the 'for' operator. Consider reviewing '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 (int i = 0; i < 5; i++)
  for (int 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 (int i = 0; i < 5; i++)
  for (int j = 0; j < 5; j++)
    A[i][j] = 0;

This diagnostic is classified as:

CWE-691
