Purchase Amount Discount
Up to 5,000 No Discount
5,001 to 10,000 10% of the amount exceeding 5000
10,001 to 20,000 20% of the amount exceeding 10,000
20,001 to 30,000 30% of the amount exceeding 20,000
More than 30,000 40% of the amount exceeding 30,000

Write a program in C to input the purchase amount and print the discount amount and the net bill amount after deducting the discount amount.

Program

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

int main()
{
    int p;
    float dis;
    printf("Enter purchase amount ");
    scanf("%d",&p);

    if(p<=5000)
    {
        dis=0;
    }
    else if(p>5000 && p<=10000)
    {
        dis=(p-5000)*(10/100.0);
    }
    else if(p>10000 && p<=20000)
    {
        dis=(p-10000)*(20/100.0);
    }
    else if(p>20000 && p<=30000)
    {
        dis=(p-20000)*(30/100.0);
    }
    else
    {
        dis=(p-30000)*(40/100.0);
    }

    printf("Discount Amount = %.2f\n",dis);
    printf("Net Bill Amount = %.2f\n",p-dis);
    return 0;
}

Output

Enter purchase amount 25648
Discount Amount = 1694.40
Net Bill Amount = 23953.60
