What is wrong with my C code? Any pointers?

Question

So basically, my C code output is suppose to look like so.
enter image description here

However I believe my IF statements are incorrect, can someone give it a look and give me some pointers?

#include <stdio.h>



int main()

{

    int a, total = 0; // Defining integers

    int n;

    int tax;

    int e;



    float subtotal;



    printf("Enter the number of days the car was rented: "); // Asking for input

    scanf("%d", &n); // Establishing number of cars



    printf("Enter the number of miles the car was driven: "); // Mile input

    scanf("%d", &a); // Establishing miles driven



    if (n > 200) {

        e = .40;

    }

    else { e = .35;

    }



    subtotal = n * 15 + a * e;



    printf("\nSubtotal: ", subtotal);



}

Answer 1

you lost something here：

#include <stdio.h>

int main()
{
    int a, n;
    float tax, e, total = 0; // Defining integers

    float subtotal;

    printf("Enter the number of days the car was rented: "); // Asking for input
    scanf("%d", &n); // Establishing number of cars

    printf("Enter the number of miles the car was driven: "); // Mile input
    scanf("%d", &a); // Establishing miles driven

    if (n > 200) {
        e = .40;
    }
    else { e = .35;
    }

    subtotal = n * 15 + a * e;

    printf("\nSubtotal: %f", subtotal);

}

gcc filename
./a.out

and here is the result:

Enter the number of days the car was rented: 7
Enter the number of miles the car was driven: 7

Subtotal: 107.449997
