10.1.6 Sign Inversion

Sign inversion is indicated by the minus sign (-). You can only specify "-immediate_value" or

"-variable_name". No sign inversion is performed if you specify 2 (or any even number of) minus signs.

Notes

• There is no support currently for sign inversion of floating point numbers.

10.1.7 Member Reference Using Dot Operator

You can only use "variable_name.member_name" for checking the members of structures and unions

using the dot operator.

Example:

class T {

public:

int member1;

char member2;

};

class T t_cls;

class T *pt_cls = &t_cls;

In this case, t_cls.member1, (*pt_cls).member2 correctly checks the members.

10.1.8 Member Reference Using Arrow

You can only use "variable_name->member_name" for checking the members of structures and unions

using the arrow.

Example:

class T {

public:

int member1;

char member2;

};

class T t_cls;

class T *pt_cls = &t_cls;

In this case, (&t_cls)->member1, pt_cls->member2 correctly checks the members.
