V6018. Constant expression in switch statement.

May 3, 2018

The analyzer detected a constant expression in a 'switch' statement. This usually indicates the presence of a logic error in the code.

Consider the following synthetic example:

int i = 1;
switch (i)
{
  ....
}

The condition of the 'switch' statement is represented by a variable whose value can be computed at compilation time. This situation could have resulted from code refactoring: the previous version of the code changed the variable's value but then it was modified and the variable turned out to be no longer assigned any value.
