1. Write a program to read x, y coordinates of 3 points and then calculate the area of a triangle formed by them and print the coordinates of the three points and the area of the triangle. What will be the output from your program if the three given points are in a straight line? 

----------------------------------------------------------------------------------------------

FLOW CHART :-

Algorithm:

Step – 1 : Start

Step – 2 : Read the values of the three coordinates 

Step – 3 : Print the values of X coordinate

Step – 4 : Print the values of Y coordinate

Step – 5 :  Calculate Area = 0.5 * fabs (x1 * (y2 – y3)+ x2 * (y3 – y2) +x3 * (y1 – y2))

Step – 6 :Print the area

Step – 7 : If area = 0.Print the points are collinear otherwise points are not collinear

Step – 8 : Stop

PROGRAM :-

#include <stdio.h>

int main()

{

int x1,x2,x3,y1,y2,y3;

float area;

printf("enter the values of x1,x2,x3  :");

scanf("%d%d%d",&x1,&x2,&x3);

printf("enter the values of y1,y2,y3  :");

scanf("%d%d%d",&y1,&y2,&y3);

printf("---------------------------\n");

area=0.5*(x1*(y2-y3)+x2*(y3-y1)+x3*(y1-y2));

 printf("the x coordinates are :\n");

printf("x1=%d\tx2=%d\tx3=%d\n",x1,x2,x3);

printf("---------------------------\n");

printf("the y coordinates are :\n");

printf("y1=%d\ty2=%d\ty3=%d\n",y1,y2,y3);

printf("---------------------------\n");

printf("the area of triangle is =%.2f\n",area);

printf("-------------------------------------------------------------------------------------\n");

printf("thank you for using our code this code is created by ECE THE WONDERS (Hemu The Smart)\n");

printf("-------------------------------------------------------------------------------------\n");

if (area==0)

{ printf("the given coordinates lies in a stright line");}

else 

{ printf("the given coordinates does not lie in a stright line");}

return 0;

}
