Answer:
b. ALTER SCHEMA
Explanation:
A database management system (DBMS) can be defined as a collection of software applications that typically enables computer users to create, store, modify, retrieve and manage data or informations in a database. Generally, it allows computer users to efficiently retrieve and manage their data with an appropriate level of security.
Database schema is the logical design of a database. In database management, the term "schema" is used to denote a representation of data while the term "instance" is used to denote an instance of time.
A database schema is a structure which is typically used to represent the logical design of the database and as such represents how data are stored or organized and the relationships existing in a database management system. There are two (2) main categories of a database schema; physical database schema and logical database schema.
A Management Studio refers to a software application or program designed and developed by Microsoft Corporation.
When you create a table using the Management Studio, the table is automatically stored in the default schema. If you want to transfer the table to a different schema, you can use the ALTER SCHEMA statement.
Chchvjvcuvggiiog. Correct
Answer:
import java.io.*;
import java.util.Scanner;
class Odd {
public static void main (String[] args) {
Scanner ele=new Scanner(System.in);//creating a scanner object.
int n,sum=0;//declaring n and sum and initializing sum with 0.
n=ele.nextInt();//taking input of the n.
int [] arr =new int[n];//declaring an array arr.
for(int i=0;i<n;i++)
{
arr[i]=ele.nextInt();//taking input of the array.
}
for(int i=0;i<arr.length;i++)
{
if(i%2!=0)//adding to the if index is odd.
{
sum+=arr[i];
}
}
System.out.println(sum);
}
}
Input:-
6
1 2 3 4 5 6
Output:-
12
Explanation:
First I have created an a scanner object ele. I have taken two integers n and sum, n for number of array elements and sum for calculating the sum of odd indexed elements hence initializing it with 0.Then I have created an array named arr.Then taking the input of the n and array elements.Then looping over the array and calculating the sum.
