Can't figure out why my C program isn't working.

Need to write a program that calculates weekly salary of each salesperson until -1 is entered.

Here's my code:

#include

int main(void)
{


float sales=0;
while (sales != -1)
{printf("Enter sales in dollars (-1 to end): "); // prompt user for input
scanf("%f\n", &sales); // obtain value


float salary;
salary = (sales * .09) + 200; // calculates salary
printf("Salary is: $ %.2f\n", salary); // give salary amount to user
}
return 0; //end program
}

Extracted text: tinclude int main(void) { float sales=0; while (sales != -1) {printf("Enter sales in dollars (-1 to end): "); // prompt user for input scanf("%f\n", &sales); // obtain value float salary; salary = (sales * .09) + 200; // calculates salary printf("Salary is: $ %.2f\n", salary); // give salary amount to user } return 0; //end program
