averaging program

ok, i want a program to average, but it wont work. tell me whats wrong.

void avg (void)
{
cout<<"This program will get the average of numbers you enter."<<endl;
float g, x, y, num, avg, num1;
cout<<"How many numbers do you want to enter? ";
cin>>num1;
num=num1;
do
{
cout<<"Please enter your numbers: ";
cin>>x;
num=num-1;
avg=avg+x;
}while(num>0);
g=avg/num1;
cout<<"The average of your numbers is: "<<g<<flush<<endl;
_getch();
}

You might need to initialize avg to zero at the beginning of your function.

Code:

---

void avg (void)
{
cout<<"This program will get the average of numbers you enter."<<endl;
float g, x, num, num1;
float avg = 0;
cout<<"How many numbers do you want to enter? ";
cin>>num1;
num=num1;
do
{
  cout<<"Please enter your numbers: ";
  cin>>x;
  num--;
  avg+=x;
}while(num>0);
g=avg/num1;
cout<<"The average of your numbers is: "<<g<<flush<<endl;
_getch();
}

why didnt i think of that before!? im so stupid sometimes

I actually ran it without the initialization on my computer, and it gave the correct results, but probably just lucky.
