Hallar el perímetro de un triángulo

Dado el lado (a, b, c) de un triángulo, tenemos que encontrar el perímetro de un triángulo. 

Perímetro: 
El perímetro de un triángulo es la suma de la longitud del lado de un triángulo. 
 

donde a, b, c son la longitud del lado de un triángulo.
El perímetro de un triángulo se puede evaluar simplemente usando la siguiente fórmula: 

Ejemplos:  

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

// 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;
}
