Write a function that returns the smallest of three floating point numbers.

#include<iostream.h>
#include<conio.h>
float smallest (float a, float b , float c);
void main()
{
      clrscr();
      float n1, n2, n3;
      cout<< "Enter three floating point numbers: ";
      cin>>n1>>n2>>n3;
      cout<<"The smallest floating number is: "<<smallest(n1,n2,n3);
      getch();
}

float smallest (float a , float b , float c)
{
      if(a<b && a<c)
            return a;
      else if(b<a && b<c)
            return b;
      else
            return c;
}
