Suppose a shop keeper offers a discount of 20% if a customer's purchased amount exceeds Rs.2000, 15% if it exceeds 1000 and 10% if exceeds 500. Write a program to read gross amount and evaluate discount and display net amount Payable.

   1:  #include<stdio.h>

   2:  #include<conio.h>

   3:  void main()

   4:  {

   5:  float gross,dis;

   6:  printf("Enter the gross amount:");

   7:  scanf("%f",&gross);

   8:  dis=0.00;

   9:  if(gross>2000.00)

  10:  dis=0.20*gross;

  11:  else if(gross>1000.00)

  12:  dis=0.15*gross;

  13:  else if(gross>500.00)

  14:  dis=0.10*gross;

  15:  printf("Gross amount %8.2f\n",gross);

  16:  printf("Discount %8.2f\n",dis);

  17:  printf("net amount %8.2f\n",gross-dis);

  18:  getch();

  19:  }
