Answer:
"double tax_rates[5]= {0.10, 0.15, 0.21, 0.28, 0.31};" is the correct answer for the above question.
Explanation:
- An array is a user-defined data type that is used to define the multiple variables of a single type in a continuous storage location.
- In the C-programming language, When the user wants to declare an array he needs to define with the help of data type and size of the array with the help of the following syntax-- "Data_type variable_name [size_of_the_array];".
- When the user wants to initialize the static value in the array then he can do that by the help of following syntax: "Data_type variable_name [size_of_the_array]={first_value,second_value,....,last_value};
- The above question asked to defined the array of tax_rates name of type double with the above-defined value then he can do that with the help of above-defined syntax (which is defined in the answer part).
Answer:
public class num9 {
public static void main(String[] args) {
int sum =0;
int num =5;
for(num =5; num<=500; num+=5){
System.out.println(num);
sum +=num;
}
System.out.println(sum);
}
}
Explanation:
- Declare and initialize the variables sum and num
- Use a for loop with the condition for(num =5; num<=500; num+=5) Since the loop will increment by 5 and run from 5 to 500
- Within the loop, add num to sum at each iteration
- Print all elements on seperate lines
- Outside the loop, print the final value of sum
Create a for loop
Option b is correct. When an overridden method is called from within a subclass, it will always refer to the version of that method defined by the subclass.
Subclasses are classes that can be created by adding new functionality to a parent class, such as new object variables or new methods. In terms of automata theory, a subclass expands the state transition table with new rows and states. However, by overriding (changing) existing functionality, the majority of OO programming languages also enable us to derive subclasses from parent classes. When implementing a class, all that is required to be specified is the new or updated functionality thanks to inheritance mechanisms between parent class and subclass.
Lines connected through a circle connect the subclasses HourlyEmployee and SalaryEmployee to the superclass Employee. The circled letter "d" stands for disjointness, which demands that the specification's subclasses be distinct. As a result, an entity can belong to only one of the specification's subclasses. An individual employee can only be paid either hourly wages or a salary; they cannot be paid both. The open sides of the inheritance (arch) symbols face the superclass.
