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 rule is classified as:
