Determining a Triangle using get and pointer
a. Define a struct data type to represent a triangle as 3 points.
b. Write a function get_triangle(), to input the three corners of a triangle and return triangle structure. Using triangle get_triangle()
c. Write a function classify(); that will analize the shape of triangle. The input should be one triangle and the result should be a pointer to a character array. Prototype is: char * classify triangle.
d. Write a main program with loop which will permit user to enter a series of triangles. For each echo the input, call the classify() fuction and print the triangles shape. (isosceles 2 sides equal, equilateral all sides same, or scalene no sides are equal).
The problem I am having so far is how call to classify and determine which shape it is.
#include <stdio.h>
typedef struct {
double x;
double y;
} point;
int main()
{
point A;
point B;
point C;
A . x=5;
A . y=4;
printf("Enter the X and Y for Point A:");
scanf ("%lg%lg", &A.x, &A.y);
printf("Enter the X and Y for Point B:");
scanf ("%lg%lg", &B.x, &B.y);
printf("Enter the X and Y for Point C:");
scanf ("%lg%lg", &C.x, &C.y);
printf ("The values entered for X and Y for Point A: %g\t %g\n",A.x,A.y);
printf("The values entered for X and Y for Point B: %g\t %g\n",B.x,B.y);
printf("The values entered for X and Y for Point C: %g\t %g\n",C.x,C.y);
return 0;
}
