V3545. AUTOSAR. Operands of the logical '&&' or the '||' operators, the '!' operator should have 'bool' type.

This diagnostic rule is based on the software development guidelines developed by AUTOSAR (AUTomotive Open System ARchitecture).

Using the logical operators '!', '&&', and '||' with variables of a type other than 'bool' is pointless; it does not seem to be the intended behavior and may be a sign of a mistake. The programmer probably intended to use a bitwise operator ('&', '|', or '~').

Example of non-compliant code:

void Foo(int x, int y, int z)
{
  if ((x + y) && z)
  {
    ....
  }
}

void Bar(int *x)
{
  if (!x)
  {
    ....
  }
}

Fixed code:

void Foo(int x, int y, int z)
{
  if ((x + y) & z)
  {
    ....
  }
}

void Foo(int x, int y, int z)
{
  if ((x < y) && (y < z))
  {
    ....
  }
}

void Bar(int *x)
{
  if (x == NULL)
  {
    ....
  }
}

This diagnostic is classified as:

  • AUTOSAR-M5.3.1
