Hi guys! I have started learning geometry and wrote a code to calculate the distance between a line(or a segment) and a point. Here is my code: [code] #include<stdio.h> #include<math.h> #include<stdlib.h> int dot_pdt(int a[],int b[],int c[]) { int ab[2],bc[2]; ab[0]=b[0]-a[0]; ab[1]=b[1]-a[1]; bc[0]=c[0]-b[0]; bc[1]=c[1]-b[1]; // printf("%d\n",(ab[0]*bc[0]+ab[1]*bc[1])); return (ab[0]*bc[0]+ab[1]*bc[1]); } int cross_pdt(int …
