# V3135. The initial value of the index in the nested loop equals 'i'. Consider using 'i + 1' instead.

The analyzer has detected a faulty or suboptimal loop. A standard pattern is used where some operation is executed for every pair of elements of an array. This operation, however, is usually not required for a pair whose members are the same element, i.e. when 'i == j'.

For example:

    for (int i = 0; i < size; i++)
      for (int j = i; j < size; j++)
        ...

It is highly possible that a more correct and effective way to traverse the arrays would probably be this:

    for (int i = 0; i < size; i++)
      for (int j = i + 1; j < size; j++)
        ...

This diagnostic is classified as:
