已知三角形三边长a，b，c，求三角形的内切圆半径和外切圆半径。c语言编程

#include <stdio.h>
#include <math.h>

int main()
{
    float a, b, c, s, inr, outr;

    printf("Enter the sides of the triangle: ");
    scanf("%f %f %f", &a, &b, &c);

    s = (a + b + c) / 2;

    inr = sqrt((s - a) * (s - b) * (s - c) / s);

    outr = a * b * c / (4 * sqrt(s * (s - a) * (s - b) * (s - c)));

    printf("Inradius of the triangle is: %.2f\n", inr);
    printf("Circumradius of the triangle is: %.2f\n", outr);

    return 0;
