    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(); 
    }

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