Is the address 7b invalid regarding cell references?

Computers and Technology
1 answer:
Lubov Fominskaja [6]3 years ago
3 0

Answer:

It is not valid

Explanation:

I'll assume the question relates to cell referencing in Microsoft Excel.

To reference a cell in Excel, we make use of the following steps:

  • Write out the cell column name first
  • Followed by the row number

7b implies that, the row number first, followed by the column name; this doesn't follow the naming convention of cells.

Hence, 7b is invalid.

Elena-2011 [213]

Answer:

The program to this question can be given as:

Program:

  //import package for user input.

import java.util.*;      

//define class

public class Budget                      

{

public static void main(String [] a)            //define main method.

{

//creating Scanner class object.

Scanner ob =new Scanner(System.in);    

//define variable.      

double budgetamount=0, amountspent=0 ,difference=0,total=0,num=0 ;        

int count = 0;                            

System.out.println("How much have you budgeted for the month? :");        //print message.

budgetamount=ob.nextDouble();                             //taking input

       while(budgetamount != 0)           //checkig number greater then 4 digite.

       {

           budgetamount= budgetamount/10;        

           ++count;

       }

       if(count>4)                 //condition

       {

       System.out.println("enter each expense, then type -999 to quit: ");

       while(num!=-999)               //taking expense  

       {

       total=total+num;                 //totaling expense

       num=scan.nextDouble();                  

       }

       if(total<=budgetamount)           //condtion for over budget.

       {

       System.out.print("under budget:");         //print message

       System.out.print(budgetamount-total);

       }

       else

       {

       System.out.print("over budget:");              //for under budget

       System.out.print(total-budgetamount);

       }

       }

       else

       {

       System.out.println("not valid");        //message for number lessthen 4 digit.    

       }                                      

}

}

output:

How much have you budgeted for the month? : 1200.55.

enter each expense, then type -999 to quit: 365.89

556.90

339.98

-999

over budget:1262.77

Explanation:

The explanation of this program can be given as:

In the above program we import the package in that is used for scanner class. This class is used for the input from the user after input we use the while loop and if-else statement. The while loop is the entry control loop It is used for input validation and if-else is used for the checking condition. Then we insert expense that is inserted by the user. Then we calculate under-budgeted and over-budgeted by conditional statement that is if-else. and at the last we print it.

il63 [147K]

Answer:

A database view is a searchable object in a database that is defined by a query. Though a view doesn't store data, some refer to a views as “virtual tables,” you can query a view like you can a table. A view can combine data from two or more table, using joins, and also just contain a subset of information.

Explanation:

A database view is a subset of a database that is based on a query that runs on one or more database tables. Database views are saved in the database as named queries and can be used to save complete queries that are frequently used.

When in global configuration mode, which steps are necessary to edit an ip address on an Ethernet interface?
katrin2010 [14]

Answer:

I. You should enter interface configuration mode.

II. Configure the IP address and subnet mask.

Explanation:

A node refers to the physical device that make up a network and are capable of sending, receiving, creating and storing data in communication.

Some examples of network nodes are modem, hubs, computer, switches, phone and printers.

In Computer networking, network devices such as routers and switches are usually configured (programmed) through the use of specific network commands commonly referred to as configs e.g show int description, config terminal (config t), show IP address, etc.

In Cisco devices, there are five (5) main types of command modes;

1. Sub-interface configuration mode.

2. Interface configuration mode.

3. Line configuration mode.

4. Router configuration method.

5. Global configuration mode.

Global configuration mode is a configuration mode that avail network engineers and end users with the ability to modify or edit the running (global) system configuration of a networking device. Thus, any change effected at the global configuration mode will affect the network device as a whole.

In global configuration mode, the steps which are necessary to edit an ip address on an Ethernet interface include;

I. You should enter interface configuration mode using the "configure terminal" command.

II. Configure the IP address and subnet mask.

See an example below;

"Router(config-if)# IP address 192.168.1.2 255.255.255.0"
