V3081. The 'X' counter is not used inside a nested loop. Consider inspecting usage of 'Y' counter.

The analyzer detected a possible error in two or more nested 'for' loops, when the counter of one of the loops is not used because of a typo.

Consider the following synthetic example of incorrect code:

for (int i = 0; i < N; i++)
  for (int j = 0; j < M; j++)
      sum += matrix[i, i];

The programmer wanted to process all the elements of a matrix and find their sum but made a mistake and wrote variable 'i' instead of 'j' when indexing into the matrix.

Fixed version:

for (int i = 0; i < N; i++)
  for (int j = 0; j < M; j++)
      sum += matrix[i, j];

Unlike diagnostics V3014, V3015, and V3016, this one deals with indexing errors only in loop bodies.

You can look at examples of errors detected by the V3081 diagnostic.
