Answer:
In a sentence: data is raw numbers, while information is organized data.
Explanation:
Data is a series of numbers or facts. A data set is a collection of data that are related (for examples all the students result in your last math exam). But it's not organized by itself... and rarely mean anything when looked at it in a raw manner.
To make sense of a data collection, you have to analyze it, calculate the mean or median of the data set for example... this is a treatment that has to be done to a data set to give it significance.. after such analysis, the result you have (mean, median, etc..) is a piece of information devired from the data.
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:
Explanation:
The Rectangle class was not provided in this question but after a quick online search I was able to find the class code. Due to this I was able to create a test code in the main Method of my program to create a Rectangle object and call it's display() method. The Test code and the output can be seen in the attached image below. While the code below is simply the Main Test Program as requested.
class Brainly {
public static void main(String[] args) {
Rectangle rectangle = new Rectangle(20, 8);
rectangle.display();
}
}
