C++ Area of Scalene Triangle

To calculate the area of a scalene triangle in C++, you can use the formula:

Area = √(s (s - a) (s - b) * (s - c))

where 's' is the semi-perimeter of the triangle, and 'a', 'b', and 'c' are the lengths of its sides.

Here are the steps to calculate the area of a scalene triangle in C++:

  1. Include the necessary header files:
#include <iostream>
#include <cmath>
  1. Define the main function:
int main() {
    // code goes here
    return 0;
}
  1. Declare variables for the lengths of the sides of the triangle:
double a, b, c;
  1. Prompt the user to enter the lengths of the sides:
std::cout << "Enter the lengths of the sides of the triangle: ";
std::cin >> a >> b >> c;
  1. Calculate the semi-perimeter 's':
double s = (a + b + c) / 2;
  1. Calculate the area using the formula:
double area = sqrt(s  (s - a)  (s - b) * (s - c));
  1. Display the calculated area:
std::cout << "The area of the scalene triangle is: " << area << std::endl;
  1. End the program:
return 0;

This code will prompt the user to enter the lengths of the sides of the scalene triangle, calculate its area using the formula, and display the result.
