Answer:
#include<iostream>
using namespace std;
int main(){
int x1,x2,x3;
int y1,y2,y3;
cout<<"Enter the value of first point(x1,y1): ";
cin>>x1>>y1;
cout<<"\nEnter the value of second point(x2,y2): ";
cin>>x2>>y2;
cout<<"\nEnter the value of third point(x3,y3): ";
cin>>x3>>y3;
}
Explanation:
first include the library iostream for use the input/output commands
then, write the main function. within the main function declare the variable which store the value of points.
after that, use the 'cout' for output. It has the function which print the value or message on the screen.
and 'cin' is used to store the value in the variable.
So, in the above code cout ask for enter the value of point and after enter value by user, cin store in the variables.
Note: you have to enter two value with space or by enter.

Answer is : 3G
Explanation:
When we comes to 3G
Packet-switched networks moves data in separate, small blocks -- packets -- based on the destination address in each packet and receives, packets and reassembled in proper sequence to make up message. Circuit-switched networks shows dedicate point-to-point connections during calls.
Circuit-switched networks used for phone calls and packet-switched networks handled data. But because of the reach of phone lines and the efficiency and low cost of data networks, the two technologies have shared chores for years.
