Operator precedence is unaffected byoperator overloading. For example,std::cout<<a?b:c;parses as(std::cout<

The precedence of these operators is the same as that for C. In addition, the unary operator defined, can be used in constant-expression in these two forms: `defined ( name )' or `defined name'. This allows the effect of #ifdef and #ifndef directives (described below) in the #if dir...

Here first assigns count the value 19, assigns incr the value 10, then adds 1 to count, and finally, assigns var the value of the rightmost expression, count+1, which is 20. The parentheses are necessary because the comma operator has a lower precedence than the assignment operator....
