C++ project help

[Circaflex]

well im doing this project for class and im terrible so far at c++ and im switching majors either way, but im still taking the class. i have this project mostly done just a few errors which i dont know how to exactly fix. take a look if you have some time.

Assignment:


Given the following main() function, write the complete form of each function called in the main(). Test your program and show all outputs.

int main()
{
int x,y, z;
// read three numbers into x, y, and z
ReadData(x,y,z);

// compute and return the total of x, y, and z
int sum=ComputeTotal(x,y,z);

// find the maximum and the minimum of x,y, and z
int max, min;
FindMaxMin(x,y,z,max,min);
cout<<" for x= "<<x<<" y= "<<y<<" z= "<<z<<endl;
cout<<"\tMaximum= "<<max<<" and Minimum= "<<min<<endl;

// find and return the average of x,y, and z
float average=FindAverage(x,y,z);
cout<<fixed<<showpoint<<setprecision(2);
cout<<" the average of x= "<<x<<" y= "<<y<<" z= "<<z<<endl;
cout<<"\tis"<<average<<endl;

// draw bargraph. For example if x=3, y=6, z=4, the output should look
//like this
// x:***
// y:******
// z:****
DrawBargraph(x,y,z);




now heres my code so far


#include <iostream>
#include <cmath>
#include <iomanip>

using namespace std;

//reads three numbers into x, y , and z
void ReadData ( int&a, int&b, int&c)
{
cout<<"Enter three numbers:";
cin>>a>>b>>c;
}

//compute and return the total of x, y, and z
void ComputeTotal( int a, int b, int c, int total)
{
total=a + b + c;
}

//find the maximum and minimum of x, y, and z
void FindMaxMin(int a, int b, int c, int&mx, int&mn)
{
if(a < b && a < c && b > c)
{
mn=a; mx=b;
}
if(a < b && a < c && b < c)
{
mn=a; mx=c;
}
if(a > b && a > c && b < c)
{
mn=b; mx=a;
}
else
{
mn=c; mx=a;
}
}

//find and return the average of x, y, and z
void FindAverage(int a, int b, int c, float average)
{
average = (a + b + c)/3.;
}

//draws the bargraphs depending on the numbers entered by the user
void DrawBargraph(int n, int p)
{
for (int n=1; n<=a; ++n)
{ cout<<"*";
}
cout<<endl;
}

int main()
{
int x,y, z;
// read three numbers into x, y, and z
ReadData(x,y,z);

// compute and return the total of x, y, and z
int sum=ComputeTotal(x,y,z);

// find the maximum and the minimum of x,y, and z
int max, min;
FindMaxMin(x,y,z,max,min);
cout<<" for x= "<<x<<" y= "<<y<<" z= "<<z<<endl;
cout<<"\tMaximum= "<<max<<" and Minimum= "<<min<<endl;

// find and return the average of x,y, and z
float average=FindAverage(x,y,z);
cout<<fixed<<showpoint<<setprecision(2);
cout<<" the average of x= "<<x<<" y= "<<y<<" z= "<<z<<endl;
cout<<"\tis"<<average<<endl;

// draw bargraph
DrawBargraph(x,y,z);

//terminate program
return 0;
}

I've got c++ but the read data commmand I haven't seen , maybe that's wrong or somethin' like that?

btw this is a hardware/oc/cooling forum :) not www.xtremecoding.com (yet)

so sry mate.

but what errors are you getting?
atm I'm at school & my classmate also can't see any mistakes in your code so..

sry,

The header that we use at school doesn't support commands like findmaxmin :(

but it seems good.
