Answer: True
Explanation: End-user computing(EUC) is the cluster of people who are non-programming nature that form a system .The system works for the computing so that they can integrate or combine the end-users into a particular computing environment.
They work by creation of the software application for the end users .This helps in the approaching and connecting of the end users in the information technology environment.Thus, the given statement is true.
Answer:
The program written in C++ is as follows'
#include<iostream>
using namespace std;
int main()
{
string names[3];
cout<<"Please enter three names: "<<endl;
for (int i = 0; i< 3;i++)
{
cin>>names[i];
}
for (int i = 2; i>= 0;i--)
{
cout<<names[i]<<endl;
}
return 0;
}
Explanation:
This line declares an array for 3 elements
string names[3];
This line prompts user for three names
cout<<"Please enter three names: "<<endl;
This following iteration lets user input the three names
for (int i = 0; i< 3;i++) { cin>>names[i]; }
The following iteration prints the three names in reverse order
for (int i = 2; i>= 0;i--) { cout<<names[i]<<endl; }
Answer:
import java.util.Scanner;
public class num9 {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
System.out.println("Enter year");
int givenYear =in.nextInt();
if(givenYear>=2101){
System.out.println("Distant Future");
}
else if(givenYear>=2001){
System.out.println("21st Century");
}
}
}
Explanation:
- Using Java programming Language
- Import Scanner class to receive user input of the variable givenYear
- Use if statement to check the first condition if(givenYear>=2101)
- Use else if statement to check the second condition if(givenYear>=2001)
- print Distant future and 21st century respectively
The two devices in a computer that should be considered "black boxes," and should never be opened due to risks involving charged capacitors are MONITOR and POWER SUPPLY.
Explanation:
- Physical contact or close proximity to the open power supply caused a discharge from the capacitor that resulted in an electric shock. Capacitors can discharge current even when not energized because they hold a charge for some time after the power is turned off.
- To do harm to your body, the voltage across the capacitor's terminals must be high enough to cause a harmful effect on you. There are no hard rules for at what voltage things become harmful, but a common 'rule of thumb' is that DC up to 48 Volt is considered low voltage. So a capacitor charged to a voltage below 48 V is fairly safe.
- A charged capacitor can be very dangerous, so it's important that you avoid coming into contact with the terminals at all times.
