Just paste this into your main function:

    double d1,d2,d3;
    printf("\nEnter first double: ");
    scanf("%lf",&d1);
    printf("\nEnter second double: ");
    scanf("%lf",&d2);
    printf("\nEnter third double: ");
    scanf("%lf",&d3);
    d1 = (d1+d2+d3)/3;
    printf("\nAverage = %lf ", d1);
