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.

Answer:
<!-- Modified by selena ramirez - for html compliance -->
Explanation:
In HTML, <!-- .. --> tag is used to insert comments in the webpage code.
Comments written inside the tag is visible only on the code, and is not displayed in the browsers when the page is requested by the client computer.
<em>Comment tag</em> is useful when there is a lot of code and multiple developers are dealing with the same code.
Comments help developers understand what changed is made and why.
Answer:
Recursive solutions can be less efficient than their iterative counterparts
Explanation:
Recursion can be defined or described as a method of solving a problem where the solution depends on solutions to smaller instances of the same problem.
It entails using iteration to ensure that smaller parts of a solution are satisfied towards solving thw overall problem.
Ita major disadvantage seems to be that it seem to be less efficient than their iterative counterparts. This is as a result of concentrating on trying to solve a smaller instances.
