i want to find discount but it is not working what i want to do

Question

#include <stdio.h>

void main()
{
      int originalprice ,discount, finalamount;
     
      printf("enter originalprice:");
      
      scanf("%d",&originalprice);

      printf("enter discount:");
      
      scanf("%d",&discount);

     finalamount = originalprice*discount;
     
     printf("%d",finalamount);
  }

Answer 1

Ok that means if you enter "100" in "enter originalprice:" and if you enter "50" in "enter discount:" means it need to show final value like 50.

My  code is here .

(If you need any changes you can edit it)

#include <stdio.h>
#include <conio.h>

void main()
{
   float original_price;
   float discount_amount;
   float discounted_amount;
   float discounted_price;
    printf("\t\t\aWELCOEM TO DISCOUNT CALCULATER BY. TN CODER");
    printf("\n\n\aEnter the original price of the item: ");
    scanf("%f", &original_price);
    printf("\n\aEnter the discount amount of the item: ");
    scanf("%f", &discount_amount);
    discounted_amount = (discount_amount*original_price)/100;
    discounted_price = (original_price-discounted_amount);
    printf("\n\n\aDiscounted amount : %f \n\n",  discounted_amount);
    printf("\aFinal price of the item : %f \n\n",  discounted_price);
}

Don't use integer use float then only it looks good becasue all amount not will be at rouded price like  this "23" , "300" some item price are like this also "23.56" "300.45" . so use float. 

Answer 2

Your problem is with the mathematics.

If you want to calculate the final price (the discount deduced from the original price), then

finalamount = originalprice*discount;

is not the right thing to do.

The correct mathematics would be

float finalamount = originalprice * (1.0f - discount);

, where discount >= 0.0 and discount <= 1.0 (that is a floating-point number between 0.0 and 1.0; if you want percentages, you should divide by 100).

And as TN CODER suggested, use floats so you can calculate fractions, not just the whole (integral) parts.
