Thread: Beginner having difficulty spotting problem

Hey guys! First post here.

I'm a C newbie trying to put together a simple program that receives the net cost of a piece of equipment and computes the new and used sale price based on the input. I'm using NetBeans on a windows 10 machine.

The program runs, but it seems to select random numbers for the output. Can anyone spot the inevitably newbie error I'm making in my code?

Thanks!

Code:

#include <stdio.h>


 main () 
{
    double net,usedprice,newprice;
    const double markup = 0.18;
    const double taxrate = 0.06;
    const double useddisc = 0.50;


    printf("Please enter Vittitow's cost:\n");
    scanf("%d", &net);
    newprice = ((net * markup)+ net) + (net * taxrate);
    usedprice = (((net * markup) + net) + net * taxrate) * usedprice;
    printf("New Price: $%.1f\nUsed Price: $%.1f\n", newprice, usedprice);
    return 0;
    
}
