C++ Data Transmission Simulation 📡

This C++ program simulates the process of creating data packets (frames) for transmission. It uses bit stuffing (padding the string with $ characters) to ensure the string length is divisible by the frame size, and it calculates the checksum for each frame.

Key Components 🔑

1. Frame Structure 🏗️

The frame structure defines the components of each packet:

• no: Frame number
• len: Frame size (fixed at 8 bytes)
• des: Destination address
• source: Source address
• data: The actual data being sent (maximum 8 characters)
• checksum: A simple checksum calculated by summing the ASCII values of the data characters.

typedef struct frame {
    int no;          // Frame number
    int len;         // Frame size (8 bytes)
    char des;        // Destination address
    char source;     // Source address
    char data[9];    // Data to be sent (up to 8 characters + null terminator)
    int checksum;    // Checksum of the data
} F;
