Answered! The user is supposed to enter two points (x,y) and then its supposed to calculate the distance between the two points…

#include <stdio.h>

#include <math.h>

struct point

{

float x;

float y;

};

int enter_a_point(struct point *pc);

float distance(struct point p1, struct point p2);

int main(void)

{

struct point pt1, pt2;

float dist;

enter_a_point(&pt1);

enter_a_point(&pt2);

dist = distance(pt1, pt2);

printf(“Distance between the points=%.2fn”, dist);

system(“pause”);

return 0;

}

int enter_a_point(struct point *pc)

{

printf(“Enter X value for point:n”);

scanf_s(“%f”, &pc->x);

printf(“Enter Y value for point:n”);

scanf_s(“%f”, &pc->y);

return 0;

}

float distance(struct point p1, struct point p2)

{

float d;

d = sqrt(pow((p2.x – p1.x), 2) + pow((p2.y – p1.y), 2));

return d;

}
