int main()
{
    int i=1,n,sum=0,c=0;
    float avg=0;

    printf("Enter 10 numbers\n");
    while(i<=10)
    {
        scanf("%d",&n);
        if(n>0)
        {
            sum=sum+n;
            c=c+1;
            avg=sum/(float)c;
        }

        i=i+1;
    }
    printf("Average of positive numbers = %f",avg);
    return 0;
