if-else program

Q. Write a C program to read quantity and price for each item. Calculate the total expenses, and if the quantity is more than 1000 than giving discount is 20%.

Ans.

/*Calculate the total expenses*/

#include<stdio.h>

#include<conio.h>

void main()

{

 int quant,dis=0;

 float tot,rate;
 clrscr();

 printf("Enter quantity : ");

 scanf("%d",&quant);

 pirntf("\nEnter rate : ");

 scanf("%f",&rate);

 if(quant>1000)

  dis=20;

 tot=(quant*rate)-(quent*rate*dis/100);

 pirntf("\nTotal expenses = %f",tot);

 getch();

}

Output :

Enter quantity :750

Enter rate : 35.54

Total expenses = 25905.000000

Enter quantity : 1450

Enter rate : 9.50

Total expenses = 12397.500000
