Question

Create a Vb interface to calculate the area of triangle and area of square depending upon the users choice.​

Answer 1

Answer:

// C++ Program to find the area  

// of triangle  

#include <bits/stdc++.h>

using namespace std;

 

float findArea(float a, float b, float c)  

{  

   // Length of sides must be positive  

   // and sum of any two sides  

   // must be smaller than third side.  

   if (a < 0 || b < 0 || c < 0 ||  

      (a + b <= c) || a + c <= b ||  

                      b + c <= a)  

   {  

       cout << "Not a valid trianglen";  

       exit(0);  

   }  

   float s = (a + b + c) / 2;  

   return sqrt(s * (s - a) *  

                   (s - b) * (s - c));  

}  

 

// Driver Code

int main()  

{  

   float a = 3.0;  

   float b = 4.0;  

   float c = 5.0;  

 

   cout << "Area is " << findArea(a, b, c);  

   return 0;  

}
