Create a program that reads coordinates of four points A B C

Create a program that reads coordinates of four points (A, B, C and D) in 2D from the

x y
A 1.2 3.6
B 1.8 2.9
C 3.6 5.7
D 9.9 3.2

and reports the user the followings:

1: Each length of sides of the triangle of points A, B and C

2: Total length of sides of the triangle

in c++

Solution

#include<iostream>

#include<cmath>

using namespace std;

int main()

{

double x1,x2,x3,x4;

double y1,y2,y3,y4;

cout<<\"enter point A\";

cout<<\"\ x : \";

cin>>x1;

cout<<\"\ y:\";

cin>>y1;

cout<<\"enter point B\";

cout<<\"\ x : \";

cin>>x2;

cout<<\"\ y:\";

cin>>y2;

cout<<\"enter point C\"

cout<<\"\ x : \";

cin>>x3;

cout<<\"\ y:\";

cin>>y3;

cout<<\"enter point D\";

cout<<\"\ x : \";

cin>>x4;

cout<<\"\ y:\";

cin>>y4;

double ab,bc,ca;

ab=sqrt(pow((x1-x2),2)+pow((y1-y2),2));

bc=sqrt(pow((x3-x2),2)+pow((y3-y2),2));
ca=sqrt(pow((x1-x3),2)+pow((y1-y3),2));
double total;

total=ab+bc+ca;

cout<<total<<\"\\t\"<<ab<<\"\\t\"<<bc<<\"\\t\"<<ca;

return 0;
