Answer:

The program to this question as follows:

Program:

//header file iostream

#include<iostream> //including file for use basic function

//using name space

using namespace std;

//main method

int main() //defining main method

{

   int a[3][3]; //defining two dimension array

   int x,y,sum=0; //defining variables

   cout<<"Enter array elements: "<<endl; //message

   for(x=0;x<3;x++) // for row

   {

       for(y=0;y<3;y++) //for column

       {

          cin>>a[x][y]; //input values from user.

       }

       

   }

   //loop for calculting sum.

   for(x=0;x<3;x++)

   {

       for(y=0;y<3;y++)

       {

       sum=sum+a[x][y];//add all elements

       }

       

   }

   cout<<"Sum: "<<sum; //print sum.

   return 0;

}

Output:

Enter array elements:  

1

2

3

4

5

6

7

8

9

Sum: 45

Explanation:

In the above C++ programming language code first, a header file is included then the main method is declared, inside a main method 2D array that is "a[][]", and an integer variable is defined that are "i, j, and sum". In the next line for loop is used, this loop is used two times that can be described as follows:

  • The first time it is used for inserting elements from user ends.  
  • The second time, it uses the sum variable to add all array elements. and in the last print function that is "cout" is used for print sum variable value.

A content-managed site can be customized _____.
natita [175]

Good question. The best answer is that it all depends on your project's specifications. Here are a few scenarios where a custom CMS would make sense:

You have security concerns or corporate security requirements that would make off-the-shelf platforms unacceptable. An example of this could be stringent security requirements that limit the amount of software licenses allowed, or that require tightening so severe that it would inhibit the ability of the platform to operate correctly. Also, remember that off-the-shelf platforms are more susceptible to random attacks by bots and other automated attackers.

You require advanced features. If you plan on having a website requiring advanced customization, evaluate if you are pushing the limits of off-the-shelf CMS platforms. An example would be software that is core to your business that must be custom built on top of the CMS platform. Future risks could be the inability to run a proper software update, or even worse, a software update breaking your custom code. It happens all the time!
