C program that calculates the total amount received in cash and online

 Here's a simplified C program that calculates the total amount received in cash and online:


Total Amount Calculator

```

#include <stdio.h>


// Define structure for payment methods

typedef struct {

    float cash;

    float online;

} PaymentMethods;


// Function to calculate total amount

float calculateTotalAmount(PaymentMethods paymentMethods) {

    return paymentMethods.cash + paymentMethods.online;

}


int main() {

    PaymentMethods paymentMethods;

    printf("Enter the amount received in cash: ");

    scanf("%f", &paymentMethods.cash);

    printf("Enter the amount received online: ");

    scanf("%f", &paymentMethods.online);


    float totalAmount = calculateTotalAmount(paymentMethods);


    printf("\nSummary:\n");

    printf("Cash: %.2f\n", paymentMethods.cash);

    printf("Online: %.2f\n", paymentMethods.online);

    printf("Total Amount: %.2f\n", totalAmount);


    return 0;

}

```


This program demonstrates the following concepts:


1. *Payment methods structure*: A structure to represent payment methods with attributes like cash and online.

2. *Total amount calculation*: A function to calculate the total amount received based on the payment methods structure.


Note that this program is a simplified example and does not cover real-world complexities like:


- Multiple payment methods (e.g., credit/debit cards, checks)

- Payment processing fees

- Currency exchange rates

- Tax calculations


To make this program more comprehensive and useful, you would need to consider these factors and add additional features and functionality.


Example Use Cases:

- A small business owner wants to track the total amount received from customers in cash and online.

- An e-commerce platform wants to calculate the total amount received from customers through various payment methods.

- A financial institution wants to track the total amount received from customers through different payment channels.

C program for Household Expenditure Calculator

 Here's a simplified C program that calculates the expenditure of everyday life to run a house based on a monthly salary and a savings goal of 50%:

// Define structure for household expenses

typedef struct {

    float rent;

    float utilities;

    float groceries;

    float transportation;

    float entertainment;

    float miscellaneous;

} HouseholdExpenses;


// Function to calculate total expenses

float calculateTotalExpenses(HouseholdExpenses expenses) {

    return expenses.rent + expenses.utilities + expenses.groceries + expenses.transportation + expenses.entertainment + expenses.miscellaneous;

}


// Function to calculate savings

float calculateSavings(float salary) {

    return salary * 0.5;

}


int main() {

    float salary;

    printf("Enter your monthly salary: ");

    scanf("%f", &salary);


    HouseholdExpenses expenses;

    printf("Enter your monthly expenses:\n");

    printf("Rent: ");

    printf("Utilities: ");

    scanf("%f", &expenses.utilities);

    printf("Groceries: ");

    scanf("%f", &expenses.groceries);

    printf("Transportation: ");

    scanf("%f", &expenses.transportation);

    printf("Entertainment: ");

    scanf("%f", &expenses.entertainment);

    printf("Miscellaneous: ");

    scanf("%f", &expenses.miscellaneous);


    float totalExpenses = calculateTotalExpenses(expenses);

    float savings = calculateSavings(salary);


    printf("\nSummary:\n");

    printf("Monthly Salary: %.2f\n", salary);

    printf("Total Expenses: %.2f\n", totalExpenses);

    printf("Savings: %.2f\n", savings);


    if (totalExpenses > salary - savings) {

        printf("\nWarning: Your expenses exceed your available income!\n");

    } else {

        printf("\nCongratulations! You have enough income to cover your expenses and savings.\n");

    }


    return 0;

}

```


This program demonstrates the following concepts:

void addTransaction(Blockchain *blockchain, Transaction transaction) {

    // For simplicity, this example assumes transactions are stored in the block data

    char data[256];

    sprintf(data, "Transaction from %s to %s for %.2f", transaction.sender, transaction.receiver, transaction.amount);

    Block block = createBlock(blockchain->blockCount, time(NULL), blockchain->blocks[blockchain->blockCount - 1].hash, data);

    addBlock(blockchain, block);

int main() {

    Blockchain blockchain;

    blockchain.blocks = malloc(sizeof(Block));

    // Create genesis block

    Block genesisBlock = createBlock(0, time(NULL), "Genesis", "Genesis Block");

    addBlock(&blockchain, genesisBlock);


    // Create transactions

    Transaction transaction1 = createTransaction("Alice", "Bob", 10.0);

    Transaction transaction2 = createTransaction("Bob", "Charlie", 5.0);

        printf("Timestamp: %ld\n", blockchain.blocks[i].timestamp);

        printf("Previous Hash: %s\n", blockchain.blocks[i].previousHash);

}


This program demonstrates the following concepts:


1. *Blockchain*: A chain of blocks, each containing a timestamp, previous hash, hash, and data.

2. *Blocks*: Individual units of the blockchain, containing a unique index, timestamp, previous hash, hash, and data.

3. *Transactions*: Data stored in the blocks, representing a transfer of value between parties.

4. *Hash function*: A function that takes input data and produces a fixed-size string of characters, used to identify blocks and transactions.


Note that this program is a highly simplified example and is not suitable for creating a real-world cryptocurrency. A real cryptocurrency would require a much more complex implementation, including:


- A secure hash function, such as SHA-256

- A consensus algorithm, such as proof-of-work or proof-of-stake

- A network of nodes to validate and relay transactions

- A wallet system for users to store and manage their cryptocurrency

- A user-friendly interface for interacting with the cryptocurrency

Simple C program to manage shopping malls inventory and sales

 Here's a simplified C program to manage a shopping mall's inventory and sales:


Shopping Mall Management System




#include <stdio.h>

#include <stdlib.h>

#include <string.h>


// Define structure for products

typedef struct {

    int id;

    char name[50];

    float price;

    int quantity;

} Product;


// Function to add products

void addProduct(Product *products, int *productCount) {

    printf("Enter product ID: ");

    scanf("%d", &products[*productCount].id);

    printf("Enter product name: ");

    scanf("%s", products[*productCount].name);

    printf("Enter product price: ");

    scanf("%f", &products[*productCount].price);

    printf("Enter product quantity: ");

    scanf("%d", &products[*productCount].quantity);

    (*productCount)++;

}


// Function to display products

void displayProducts(Product *products, int productCount) {

    printf("Product List:\n");

    for (int i = 0; i < productCount; i++) {

        printf("ID: %d, Name: %s, Price: %.2f, Quantity: %d\n",

               products[i].id, products[i].name, products[i].price, products[i].quantity);

    }

}


// Function to sell products

void sellProduct(Product *products, int productCount) {

    int productId;

    printf("Enter product ID to sell: ");

    scanf("%d", &productId);

    for (int i = 0; i < productCount; i++) {

        if (products[i].id == productId) {

            if (products[i].quantity > 0) {

                products[i].quantity--;

                printf("Product sold successfully!\n");

            } else {

                printf("Product out of stock!\n");

            }

            return;

        }

    }

    printf("Product not found!\n");

}


int main() {

    Product products[100];

    int productCount = 0;

    int choice;


    while (1) {

        printf("Shopping Mall Management System\n");

        printf("1. Add Product\n");

        printf("2. Display Products\n");

        printf("3. Sell Product\n");

        printf("4. Exit\n");

        printf("Enter your choice: ");

        scanf("%d", &choice);


        switch (choice) {

            case 1:

                addProduct(products, &productCount);

                break;

            case 2:

                displayProducts(products, productCount);

                break;

            case 3:

                sellProduct(products, productCount);

                break;

            case 4:

                exit(0);

            default:

                printf("Invalid choice!\n");

        }

    }


    return 0;

}



This program allows users to:


1. Add products to the inventory

2. Display the list of products

3. Sell products (reduce quantity)


Note that this is a simplified program and doesn't include features like user authentication, data validation, or file persistence.
