main.cpp

#include<iostream>
#include<cmath>
using namespace std;
#define IN_FILE "lab5.dat"
#define OUT_FILE "lab5.txt"

/* function prototype */
void find_two_radii (double a, double b, double c, double*radius_inside, double*radius_outside) {
   double s = 1.0/2*(a+b+c);
   *radius_inside = sqrt((s-a)*(s-b)*(s-c));
   *radius_outside = 4*sqrt(s*(s-a)*(s-b)*(s-c));
}

int main()
{
   double a=10;
   double b=12;
   double c=15;
   double ri,ro;
   find_two_radii(a,b,c,&ri,&ro);
   cout<<"Radius outside : "<<ro<<endl;
   cout<<"Radius inside : "<<ri<<endl;

   return 0;
