Compare Three Numbers

[Natalyias77]

I am trying to write a program that compares 3 numbers with the output labeling high, med,and low. It works for the highest and lowest, but I am having challenges trying to figure out how to calculate for the medium.

Here is my program. In the third function it grabs what 'a' is. It ignores my if...

#include "stdafx.h"
#include <iostream>

using namespace std;

double larger(double a, double b, double c);
double lowest(double a, double b, double c);
double medium(double a, double b, double c);


int main()
{
double one, two, three;

cout << "Enter three numbers: \n";
cin >> one >> two >> three;
cout << endl;

cout << "High: " << larger(one, two, three)<< endl;
cout << "Low: " << lowest(one, two, three) << endl;
cout << "Med: " << medium(one, two, three) << endl;

system ("pause");

return 0;
}

double larger(double a, double b, double c)
{
double max = a;

if (b > max) max = b;
if (c > max) max = c;

return max;
}

double lowest(double a, double b, double c)
{
double min = a;

if (b < min) min = b;
if (c < min) min = c;

return min;
}

double medium(double a, double b, double c)
{

double med = a;

if (a < larger(a, b, c) && a > lowest(a, b, c));

return med;

}

Thanks,
Shirley

It ignores my if...

It does not ignore your if; the problem is that there is no code to be executed when the if is found to be true. After an if statement, the semi-colon marks the END of the code to be executed when the if is found to be true.

if (a < larger(a, b, c) && a > lowest(a, b, c));

I'll add a bit to your line of code to show you the code that is executed when the if is found to be true:

if (a < larger(a, b, c) && a > lowest(a, b, c)) */ HERE IS THE CODE THAT IS EXECUTED - THERE IS NOTHING HERE */ ;

So what would you suggest? The trick is I can only do 3 comparisons.
I can see where my third function is returning a empty value.

Any thoughts would be great.

So I updated my code but am still unable to get the 'middle (med)' value.

Thoughts?

#include "stdafx.h"
#include <iostream>

using namespace std;

double larger(double a, double b, double c);
double lowest(double a, double b, double c);
double medium(double a, double b, double c);


int main()
{
double one, two, three;

cout << "Enter three numbers: \n";
cin >> one >> two >> three;
cout << endl;

cout << "High: " << larger(one, two, three)<< endl;
cout << "Low: " << lowest(one, two, three) << endl;
cout << "Med: " << medium(one, two, three) << endl;

system ("pause");

return 0;
}

double larger(double a, double b, double c)
{
double max = a;

if (b > max) max = b;
if (c > max) max = c;

return max;
}

double lowest(double a, double b, double c)
{
double min = a;

if (b < min) min = b;
if (c < min) min = c;

return min;
}

double medium(double a, double b, double c)
{

double med =a;

if (b < larger(a, b, c) && b > lowest(a, b, c))
{
b = med;
}

return med;
