QuestionTo bool or not to bool in C/C++ ? Pin

An attempt to learn and make sense of evaluating results. 

Making these  assumptions, right or wrong

“bool” is not “standard” C/C++ type  
when “condition”  such as in “if(condition)” evaluates to true , it is binary zero
thus  if(condition == 0)  would make better sense 
then if(condition) 

most “well written functions return x” , x being mostly  zero when function is successful 
when function fails – the return value is (generally) -1  or positive value identifying the error 
then same as above  - if(function (z) == 0) should prevail. 

Of course explicit evaluation of result to zero could prevent hard to locate bugs when these commonly used implicit evaluation conventions  are not followed by author of the code.. 

Any other views / comments would be appreciated.
