Why does this C++ code compile? What does it do? -

this question has answer here:

i had problem when accidentally deleted method name. code went from

bool bret = methodname(pdata, poutfilename);

to

bool bret = (pdata, poutfilename);

but still compiled? code do? mean? seems return true, case (even if pdata null)?

any ideas welcome!

it "comma operator"

evaluates first operand , discards result, , evaluates second operand , returns value (and type).
