Find Perimeter of a triangle

Given side (a, b, c) of a triangle, we have to find the perimeter of a triangle. 

Perimeter :
Perimeter of a triangle is the sum of the length of side of a triangle. 

where a, b, c are length of side of a triangle.
Perimeter of a triangle can simply be evaluated using following formula : 

Examples :  

Input : a = 2.0, b = 3.0, c = 5.0
Output : 10.0


Input : a = 5.0, b = 6.0, c = 7.0 
Output : 18.0

C++

// A simple C++ program to find the perimeter
// of triangle
#include <iostream>
using namespace std;

// Function to find perimeter
float findPerimeter(float a, float b, float c)
{

    // Formula for finding a perimeter
    // of triangle
    return (a + b + c);
}

// Driver Code
int main()
{
    float a = 2.0, b = 3.0, c = 5.0;
    cout << findPerimeter(a, b, c);
    return 0;
}

{
    float a = 2.0, b = 3.0, c = 5.0;
    printf("%f", findPerimeter(a, b, c));
    return 0;
}

    static float findPerimeter(float a, float b, float c)
    {
        // Formula for Perimeter of triangle
        return (a + b + c);
    }

    // Driver method
    public static void main(String[] args)
    {
        float a = 2.0, b = 3.0, c = 5.0;
        System.out.println(findPerimeter(a, b, c));
    }
}
