can someone tell me why it won't read maximum and minimum?

``````float FindMaxMin(int x, int y, int z, float &max, float &min)
{
//FindMax
if (x > y && x > z)
{return x;}

if (y > x && y > z)
{return y;}

else
{return z;}

//FindMin
if (x < y && x < z)
{return x;}

if (y < x && y < z)
{return y;}

else
{return z;}

}``````

Its code like this make me wanna pull my hair.

nevermind i changed it to this and it workd

``````#include "stdafx.h"
#include <iostream>
#include <iomanip>
using namespace std;

//------------------------prototypes----------------------------------
void ReadData(int &x, int &y, int &z);

//--------------------------------------------------------------------

{
//read data into x, y, and z
int x, y, z;

//find the maximum and the minimum of x, y, and z
int max, min;

//show all results

else
{max = z;}

``````void FindMaxMin(int x, int y, int z, int &max, int &min)

else
{max = z;}

//FindMin
if (x < y && x < z)
{min = x;}

if (y < x && y < z)
{min = y;}

else
{min = z;}

}``````

still wrong.

There's a mismatch on your signatures

``````ShowAll(x, y, z, average, max, min);
vs.
void ShowAll(int x, int y, int z, float average, int min, int max)``````
