Marking a variable that is unchanged after initialization ``const`` is an indication to future maintainers that "no this isn't updated, and it's not supposed to be". ``const`` should be used in these situations in the interests of code clarity.

== Noncompliant Code Example

----
public bool Seek(int[] input)
{
  int target = 32;  // Noncompliant
  foreach (int i in input)
  {
    if (i == target) 
    {
      return true;
    }
  }
  return false;
}
----

== Compliant Solution

----
public bool Seek(int[] input)
{
  const int target = 32;
  foreach (int i in input)
  {
    if (i == target)
    {
      return true;
    }
  }
  return false;
}
