Write a program to calculate the area of a triangle using function

#include<stdio.h> #include<math.h> float triangle(float,float,float); int main() { float a,b,c; printf("Enter the sides of triangle: \n"); scanf("%f%f%f",&a,&b,&c); if(a<b+c && b<c+a && c<a+b) printf("Area of triangle is %f",triangle(a,b,c)); else printf("This sides does not form triangle."); return 0; } float triangle(float x, float y, float z) { float s,A; s=(x+y+z)/2; A=sqrt(s*(s-x)*(s-y)*(s-z)); return A; }

**Output**

Enter the sides of triangle:

3

4

5

Area of triangle is 6.000000
