Answer:
A) 2
Explanation:
In this code snippet provided which shows the use of the switch statement in C++. Two variables have been declared and initialized.
int x=55 and int y = 5;
The condition of the switch statement (x%7) evaluates to 6. Therefore case 6: gets executed which is y-3 and this is equal to 2 since the initial value of y was 5. The output statement cout << y << endl; prints 2 to the console
