C program uses macro function to calculate salesperson's salary

Question

The monthly compensation policy of a laptop manufacturing company for its sales staff is as follows -

Minimum basic salary: 3000.00

Bonus per computer sold: 200.00

Commission on total monthly sales: 5%

Since the price of laptops is constantly changing, the sales price of each laptop The beginning of the month is fixed every month.

Solution

bonus = BONUS_RATE * quantity ;
commission = COMMISSION * quantity * price ;

The total salary is calculated using the formula given below-

Gross salary = basic salary + (quantity * bonus rate)
+ (quantity * Price) * commission rate

Example

The following is a C program that uses macro functions to calculate sales staff wages-

Live demonstration

#define BASIC_SALARY 3000.00
#define BONUS_RATE 200.00
#define COMMISSION 0.05
main(){
   int quantity ;
   float gross_salary, price ;
   float bonus, commission ;
   printf("number of items sold and their price</p><p>") ;
   scanf("%d %f", &quantity, &price) ;
   bonus = BONUS_RATE * quantity ;
   commission = COMMISSION * quantity * price ;
   gross_salary = BASIC_SALARY + bonus + commission ;
   printf("</p><p>");
   printf("Bonus = %6.2f</p><p>", bonus) ;
   printf("Commission = %6.2f</p><p>", commission) ;
   printf("Gross salary = %6.2f</p><p>", gross_salary) ;
}
