(Find the Minimum) Write a program that inputs three double-precision, floating-point numbers and passes them to a function that returns the smallest number.

Question

What will be an ideal response?

Answer 1

```
// Determine the smallest of 3 numbers.
#include
using namespace std;

double smallest( double, double, double ); // function prototype

int main()
{
double x; // first input
double y; // second input
double z; // third input

cout << "Enter three numbers: ";
cin >> x >> y >> z;

// determine smallest value
cout << "The smallest value is " << smallest( x, y, z ) << endl;
} // end main

// smallest returns the smallest of a, b and c
double smallest( double a, double b, double c )
{
if ( a < b && a < c )
return a;
else if ( b < a && b < c )
return b;
else
return c;
} // end function smallest
