Chapter 5,Problem i: Let Us C

Problem Statement:

If the lengths of the sides of a triangle are denoted by a, b,
and c, then area of triangle is given by
area = S(S − a)(S − b)(S − c)
where, S = ( a + b + c ) / 2

Solution:

//Ahmad Furqan

//P5.i

#include <iostream>

#include <conio.h>

using namespace std;

float triarea(int a, int b, int c)

{

int s;

float area;

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

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

return area;

}

void main(void)

{

int a, b, c;

cout << "Enter triangle side lengths:" << endl;

cout << "a: ";

cin >> a;

cout << "b: ";

cin >> b;

cout << "c: ";

cin >> c;

cout << "Area of the triangle is: " << triarea(a, b, c);

_getch();
