C/C++ Math Order of Operation

Question

So I know that C++ has an Operator Precedence and that

int x = ++i + i++;

is undefined because pre++ and post++ are at the same level and t

Answer 1

If you look at the C++ operator precedence and associativity, you'll see that the division operator is Left-to-right associative, which means this will be evaluated as (1/2)/3, since:

Operators that are in the same cell (there may be several rows of operators listed in a cell) are evaluated with the same precedence, in the given direction. For example, the expression a=b=c is parsed as a=(b=c), and not as (a=b)=c because of right-to-left associativity.
