Answer 1

I didn't understand your question

Answer 2

Program is given below.

Explanation:

//Header files

   #include <stdio.h>

   #include <stdlib.h>

    struct Point{

        int x;

        int y;

    };

//Defining function

      int isTriangle(Point*p1, Point*p2, Point*p3)

       {

          int c;

//Checking for collinearity

          c = ((p2->x - p1->x)*(p3->y - p1->y))

                != ((p2->y - p1->y)*(p3->x - p1->x));

           printf("%d",c);

        return c;

       }

       int main(){

           struct Point a1;

           struct Point a2;

           struct Point a3;

           //Values of Point 1

           a1.x=3;

           a1.y=4;

           //Values of Point 2

           a2.x=2;

           a2.y=1;

           //Values of Point 3

           a3.x=1;

           a3.y=5;

         //Calling the defined function

           isTriangle(&a1, &a2, &a3);

       }
