The Meaning of Rule 12.6?

[Hammer]

I am trying to understand this rule and need someone to clarify its exact meaning.

which of the following are violations of Rule 12.6?

Code:

if((x==y)|(y==a))/*Violation?, could || have been meant?*/
   {    

   }

This is a violation of the old equivalent rule 36 but is it still a violation now?

Code:

a=a+y+x+(x||y);
/*Violation, effectively boolean expression used with + operator*/

Code:

int32_t x=5;
int32_t y=11;

if(x||y) /*Could this be a violation??? because x and y are not effectively boolean*/
   {
      
   }

Thanks for you help!

Code:

if ( ( x == y ) | ( y == a ) ) /*Violation?, could || have been meant?*/
   {    
  
   }

a = a + y + x + ( x || y );

These are violations of 12.6. as effectively boolean expressions are being used as the operand of an operator other than &&, || and !.

Code:

int32_t x = 5;
int32_t y = 11;

if ( x || y ) /*Could this be a violation??? because x and y are not effectively boolean*/
   {
      
   }

This is a violation of the first sentence of 12.6.
