V3524. AUTOSAR. The value of uninitialized variable should not be used.
This diagnostic rule is based on the software development guidelines developed by AUTOSAR (AUTomotive Open System ARchitecture).
If a variable of a POD type isn't initialized explicitly and doesn't have an initializer by default, its value will be undefined. Usage of such value will lead to undefined behavior.
Simple synthetic example:
int Aa = Get();
int Ab;
if (Ab) // Ab - uninitialized variable
Ab = Foo();
else
Ab = 0;Usually errors of using uninitialized variables occur through misprints. For example, it may appear that a different variable should be used in this place. Correct code variant:
int Aa = Get();
int Ab;
if (Aa) // OK
Ab = Foo();
else
Ab = 0;This diagnostic is classified as:
