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.
