    int i=1,n,sum=0,c=0;
    float avg=0;

    cout<<"Enter 10 numbers\n";
    while(i<=10)
    {
        cin>>n;
        if(n>0)
        {
            sum=sum+n;
            c=c+1;
            avg=sum/(float)c;
        }

        i=i+1;
    }
    cout<<"Average of positive numbers = "<<avg;
    return 0;
