Answer:
output.write("Hello, World")
Explanation:
A printWriter object (An instance of a class) is contained in a variable called output, to access the write method we use the dot (.) operator to access the write method of the output object and hence, output.write() outputs any string it takes as argument. this is a very interesting OOP (Object oriented programming concept).
There´s PowToon, GoAnimate, ToonBoom. There are more, but these are the ones that I know about. I hope that I helped. Have a good day!
Oracle, DB2, and Microsoft SQL Server are examples of RDBMS. Therefore, the <u>correct option of this question is (c)</u> i.e. RDBMS.
A software used to store, query, and retrieve data stored in a relational database is referred to as a relational database management system (RDBMS). In RDBMS, data is represented in tables with rows and columns.
The RDBMS handles administrative functions such as managing data access, storage and performance. To perform these administrative services, RDBMS provides an interface between the database, applications and users.
Some features of RDBMS are described below:
- RDBMSs are more secure, faster and easier to work with.
- More than one user can have access to RDBMS at a point of time.
- RDBMS supports distributed databases.
- RDBMS can store a vast amount of data.
- Only the data in the form of tables is managed by RDBMS.
- Data redundancy is reduced in RDBMS using primary keys and indexes.
Thus, Oracle, DB2, and Microsoft sql server are example of RDBMS.
<u>While the other ptions (a) supply chain management and (b) erp applications are not correct because:</u>
- Supply chain management is a centralized management process that handles the flow of goods and services, such as movement and storage of raw materials, inventory, finished goods, and delivery of the final product.
- Enterprise resource planning (ERP) applications refers to software used in organizations to manage day-to-day business operations such as project management, risk management and compliance, procurement, accounting and supply chain operations.

#SPJ4
Answer:
// Here is code in C++.
#include <bits/stdc++.h>
using namespace std;
int main()
{
// declare and initialize variables
float item_cost=26.50;
float federal_tax=0.2,state_tax=0.05;
float cust_pay=50;
// calculate change
float change=cust_pay-(item_cost*(1+federal_tax+state_tax));
cout<<"change returned to customer is:$"<<change<<endl;
return 0;
}
Explanation:
Declare and initialize item cost with 26.5, federal tax with 0.2(i.e 20%) and state tax with 0.05(i.e 5%).After that initialize customer pay with 50. Then calculate total cost of item and subtract it from cust_pay.This will be the change amount that should be returned to customer.
Output:
change returned to customer is:$16.875
