Programa para encontrar el elemento más pequeño entre tres elementos

Dados tres números. La tarea es encontrar el más pequeño entre los tres números dados.
 

Ejemplos: 
 

Input: first = 15, second = 16, third = 10
Output: 10

Input: first = 5, second = 3, third = 6
Output: 3

Acercarse: 
 

1. Compruebe si el primer elemento es más pequeño que el segundo y el tercero. Si es así, imprímelo.
2. De lo contrario, compruebe si el segundo elemento es más pequeño que el primero y el tercero. Si es así, imprímelo.
3. De lo contrario, el tercero es el elemento más pequeño e imprimirlo.

A continuación se muestra la implementación del enfoque anterior:

    if (a <= b && a <= c)
        cout << a << " is the smallest";
 
    else if (b <= a && b <= c)
        cout << b << " is the smallest";
 
    else

    return 0;
