While purchasing certain items, a discount of 10% is offered if the quantity purchased is more than 1000. If quantity and price per item are input through the keyboard, write a program to calculate the total expenses.

#include<stdio.h>
main()

{
int qty,dis=0; /*initializing is required as if tot<1000, then discount is 0*/
float rate, tot;

printf ("Enter quantity and rate: ");
scanf ("%d %f", &qty, &rate);

if (qty>1000)
dis=10;

tot=(qty*rate) - (qty*rate*dis/100);

printf("Total expenses = Rs. %f", tot);

}
