c++ - Order of calls and side effects -


consider operation :

int = f1(mystream)*f2(mystream)+f3(mystream);

where f1, f2, f3 of following form :

int f(std::istream&)

or 

int f(std::ostream&)

do have guarantee f1, f2 , f3 executed in order ?

no. individual subexpressions not sequenced respect 1 another. guaranteed 1 function call completes before starts, order of 3 function calls indeterminate.
