Write a C program that: 1. Accepts the total purchase amount, customer type, and season from the user. 2. Uses nested if-else statements to calculate and display the final amount after applying the discount.

Here is a C Program for Customer and Day Based Shop Management Program 

#include <stdio.h>

int main() {

    char name[20];

    float totalPurchase, finalAmount;

    int customerType;

    int season;      

    float discount = 0.0;

    printf("Enter Your name: ");

    scanf("%s", name);

    printf("_________________________________________________________");

   

    printf("\nEnter the total purchase amount that you Purchased: Rs.");

    scanf("%f", &totalPurchase);

   

    printf("\nEnter customer type (1 for Regular, 2 for Premium, 3 for VIP): ");

    scanf("%d", &customerType);

   

    printf("Enter season (1 for Normal, 2 for Holiday): ");

    scanf("%d", &season);

   

    if (customerType == 1) {

        if (season == 1) {

            discount = 0.05;

        } else if (season == 2) {

            discount = 0.10;  

        }

    } else if (customerType == 2) {

        if (season == 1) {

            discount = 0.10;

        } else if (season == 2) {

            discount = 0.15;  

        }

    } else if (customerType == 3) {

        if (season == 1) {

            discount = 0.15;

        } else if (season == 2) {

            discount = 0.20;

        }

    } else {

        printf("Invalid customer type.\n");

        return 1;

    }

   

   

    if (totalPurchase > 1000) {

        discount += 0.05; // Additional 5% discount

    }

   

   

    finalAmount = totalPurchase * (1 - discount);

        printf("Discount= %0.2f", totalPurchase - finalAmount);

   

    printf("\nDear %s, ", name);

    // Display the final amount

    printf("The final amount after applying the discount is: Rs.%.2f\n", finalAmount);

    printf("Thanks For Shopping...");

    return 0;
