Answer:
The correct answer to the following question will be "Digital Forensics".
Explanation:
- Digital forensics is a field of forensics that involves the analysis and retrieval of materials found in electronic devices, sometimes related to cybercrime.
- The objective of digital forensics methodologies would be to check, maintain and evaluate evidence on computing systems to find possible evidence for a trial. In the initial days of computing, an individual investigator could process files because the power consumption was so small.
Therefore, Digital Forensic is the right answer.
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<<" ";
