I have an issue regarding the rule violation in which I'm using a 2D array inside a structure
and apparently The Rule 17.4 says it isn't compliant
. Is Declaring arryas inside a structure/union not compliant and why is it so? What exactly is the alternative for it?
Help would be appreciated ASAP. Following is the example code. Thanks in advance.
Code: Select all
void func1(unsigned char abc);
typedef struct teststructure
unsigned char abc;
void func1(unsigned char abc)
float fData = 54.0;
TEST.buf = fData;

This is most likely a false positive from the static analysis tool you are using.
Rule 17.4 bans pointer arithmetic but in your sample you use array indexing only, so it is compliant.
I suggest contacting your tool vendors support.

There is no violation of rule 17.4.
