[C/C++] Program to Find The Area of Any Triangle

Heron’s Formula for the area of a triangle(Hero’s Formula) A method for calculating the area of a triangle when you know the lengths of all three sides. Let a,b,c be the lengths of the sides of a triangle.

Heron’s formula states that the area of a triangle whose sides have lengths a, b, and c is

where s is the semiperimeter of the triangle; that is,

C Code

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

void main()
{
 float a, b, c, s, area;

 printf("Enter Value For a: ");
 scanf("%f", &a);

 printf("Enter Value For b: ");
 scanf("%f", &b);

 printf("Enter Value For c: ");
 scanf("%f", &c);

 s = (a+b+c)/2;
 area = sqrt(s*(s-a)*(s-b)*(s-c));

 printf("Area of Triangle: %.3f", area);

 getch();
}

C++ Code

#include <iostream>
#include <math.h>

using namespace std;

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

 cout << "Enter Value For a: ";
 cin >> a;

 cout << "Enter Value For b: ";
 cin >> b;

 cout << "Enter Value For c: ";
 cin >> c;

 s = (a+b+c)/2;
 area = sqrt(s*(s-a)*(s-b)*(s-c));

 cout << "Area of Triangle: " << area << endl;

 return 0;
}
