Question

Given the declarations

enum Days {YESTERDAY, TODAY, TOMORROW};
Days day = TODAY;

what is the value of the expression int(day) ?

Answer 1

Answer: 1

In the first line we have declared an enumeration of the name 'Days' which has three values.

In the second line we create an object/variable (day) of enum and declare it with TODAY. What happens here is the index value of TODAY is assigned to the variable 'day'. i.e. 1 is assigned to day.

So the value of int(day) = 1

main.cpp 2 #include <iostream> 4 using namespace std; 6 int main() -{ enum Days {YESTERDAY, TODAY, TOMORROW} ; Days day = TODAY; cout<<int(day); return 0; 12 } input ... Program finished with exit code o Press ENTER to exit console.
