Answer:
The program is as follows:
#include <iostream>
#include <iomanip>
using namespace std;
int main(){
    int num1, num2, num3;
    cin>>num1>>num2>>num3;
    cout << fixed << setprecision(2);
    cout<<(num1 + num2 + num3)/3<<" ";
    cout<<num1 * num2 * num3<<" ";
    return 0;
}
Explanation:
This declares three integer variables
    int num1, num2, num3;
This gets input for the three integers
    cin>>num1>>num2>>num3;
This is used to set the precision to 2
    cout << fixed << setprecision(2);
This prints the average
    cout<<(num1 + num2 + num3)/3<<" ";
This prints the product
    cout<<num1 * num2 * num3<<" ";
 
        
             
        
        
        
Answer:
The answer is below
Explanation:
There are cases where the use of a NULL value would be appropriate in a computer programming situation. These cases can be summarily described below:
The first case is in a situation where the value of the attribute of a certain element is known to exist, but the value can not be found
The second case is in a situation where the value of the attribute of a certain element is not known whether it exists or not.
 
        
             
        
        
        
Answer:
  Information virtualization is the process of representing the abstract data such as numeral number and text into the form of visual which is human can easily understand. 
The main challenges faced by the information visualization researchers are: 
- The main challenge which are faced by the information virtualization is during the data importing and also cleaning in the system. 
 - It also not able to access the large amount of the data easily from the system. 
 - Due to the poor selection of the scale and the coordinate rotation it also lead to the data distortion.
