total commission is correct?

[justin123]

Here the code:

#include<iostream>

using namespace std;

void sales_amount();
//void commission_percentage();
//void commission_total();

Am i wrong about my code to follow the problem?
Thanks

# include <iostream>
# include <limits.h>
using namespace std;


void calculatecomm(float &y)
{
    y = float(y) * 0.1;
}

void displaycomm(float x)
{
    cout << " The commission is : " << x << " $ " << endl;
}

void totalcomm(float total)
{
    cout << " total : " << total << endl;
}

float getsales(void)
{
    int var = 0;
    cout << "Enter sales amount -> ";
    cin >> var;

    return var;
}

int main()
{
    float comSum = 0;

    for (int i=0;;i++)
    {
        float tmpVar = getsales();
        if(tmpVar<0)break;
        calculatecomm(tmpVar);
        displaycomm(tmpVar);
        comSum += tmpVar;
    }

    totalcomm(comSum);

    cin.ignore(INT_MAX,'\n'));
}

This is the job of the functino totalcomm(int);

[justin123]
