 Given: The expression is floor (x*10+0.5)/10, where x is 3.5, 3.45, 3.76, 3.234, and 3.4567.
To find:Â The value of the expression, floor (x*10+0.5)/10, where x is 3.5, 3.45, 3.76, 3.234, and 3.4567.
Solution:
The output of the aforementioned statement, (x*10+0.5)/10, when:
x=3.5
The output of the aforementioned expression will evaluate to 3.500000. On substituting the value of x as 3.5, the expression will be evaluated. Then the function named ‘floor()’ is applied, which will return the largest double value which is smaller than or equal to integer x. The value it will return will be of type, double.
The following is the sample code:
The output of the above function will look like:
x=3.45
The output of the aforementioned expression will evaluate to 3.500000. On substituting the value of x as 3.45, the expression will be evaluated. Then the function named ‘floor()’ is applied, which will return the largest double value which is smaller than or equal to integer x. The value it will return will be of type, double.
The following is the sample code:
The output of the above function will look like:
x=3.76
The output of the aforementioned expression will evaluate to 3.800000. On substituting the value of x as 3.76, the expression will be evaluated. Then the function named ‘floor()’ is applied, which will return the largest double value which is smaller than or equal to integer x...

You can think of a tile as a square on the board on which the game will be played. We will come back to this class later. For the moment you can leave it empty while you work on creating classes that represents characters in the game. • Write an abstract class Fighter which has the following private fields: - A Tile field named position, representing the fighter's position in the game. A double field named health, representing the fighter's health points (HP). An int field named weaponType, representing the type of weapon the fighter is using. This value is used to rank different weapon types: higher values indicate higher weapon ranks. -An int field named attackDamage, representing the fighter's attack power.
