Floating$-$point numbers are exact. T or F What is the output of this code: bool result $=$ false; cout $<<$The result is $<<$ result $<<$ endl; What is the output of this code in C$++$: int number $=5$; cout $<<$The size of number is $<<$ sizeof$($number$)<<$ endl; int length $=12,$ width $=5,$ area; $//$ this is valid C$++$ code; What is the value of myNumber after this assignment: int myNumber $=25\%4$ ; It is a good programming practice, to declare all named constants as global constants. const double TAX$\_$RATE $=8\mathrm{.}75$ ; $//$ This is an example of named constant.
