Before diving into server-based polynomial evaluation, ensure you have the following prerequisites:

  • Basic knowledge of C programming.
  • A C development environment set up on your computer.

Step-by-Step Implementation

We will break down the implementation into key steps, explaining each one in detail:

  1. Include Necessary Header Files: Start by including the required header files for socket programming and standard C libraries.
  2. Define Maximum Degree: Set a maximum degree for the polynomials that your program can handle.
  3. Polynomial Evaluation Function: Define a function `evaluatePolynomial` to compute the value of a polynomial for a given set of coefficients and an input value.
  4. Main Function: In the `main` function, handle the following tasks:
    • Check command-line arguments.
    • Parse the port number and polynomial degree.
    • Read the polynomial coefficients from the command-line arguments.
    • Create and configure the server socket.
    • Listen for incoming connections.
  5. Accept and Serve Clients: In the main loop:
    • Accept incoming client connections.
    • Read the value of `x` from the client.
    • Calculate the polynomial value using the `evaluatePolynomial` function.
    • Send the result back to the client.
  6. Clean Up: Close the server socket when done serving clients.

Putting It All Together

Find the complete C program, along with explanations for each code block, in the snippet below:

```c #include #include #include #include #include #include // Define the maximum degree of the polynomial #define MAX_DEGREE 10 // Function to evaluate a polynomial double evaluatePolynomial(double coefficients[], int degree, double x) { double result = 0.0; for (int i = 0; i <= degree; i++) { result += coefficients[i] * pow(x, i); } return result; } int main(int argc, char *argv[]) { // Check if the correct number of arguments are provided if (argc != 3) { printf("Usage: %s ... \n", argv[0]); return 1; } // Parse command line arguments int port = atoi(argv[1]); int degree = atoi(argv[2]); // Check if the degree is within the allowed range if (degree > MAX_DEGREE) { printf("Degree exceeds the maximum allowed degree of %d.\n", MAX_DEGREE); return 1; } double coefficients[MAX_DEGREE + 1]; // Read coefficients from command line arguments for (int i = 0; i <= degree; i++) { coefficients[i] = atof(argv[3 + i]); } // Create a socket int serverSocket = socket(AF_INET, SOCK_STREAM, 0); if (serverSocket == -1) { perror("Socket creation failed"); return 1; } // Define server address struct sockaddr_in serverAddr; serverAddr.sin_family = AF_INET; serverAddr.sin_port = htons(port); serverAddr.sin_addr.s_addr = INADDR_ANY; // Bind the socket to the server address if (bind(serverSocket, (struct sockaddr *)&serverAddr, sizeof(serverAddr)) == -1) { perror("Socket binding failed"); close(serverSocket); return 1; } // Listen for incoming connections if (listen(serverSocket, 5) == -1) { perror("Socket listening failed"); close(serverSocket); return 1; } printf("Server listening on port %d...\n", port); while (1) { // Accept incoming connections int clientSocket = accept(serverSocket, NULL, NULL); if (clientSocket == -1) { perror("Socket accept failed"); continue; } // Read the value of x from the client double x; if (read(clientSocket, &x, sizeof(double)) == -1) { perror("Error reading x from client"); close(clientSocket); continue; } // Calculate the polynomial value at x double result = evaluatePolynomial(coefficients, degree, x); // Send the result back to the client if (write(clientSocket, &result, sizeof(double)) == -1) { perror("Error sending result to client"); close(clientSocket); continue; } close(clientSocket); } // Close the server socket close(serverSocket); return 0; } ```


Creating a C program to compute polynomials on a server is a valuable skill for anyone interested in network programming or mathematical computation.
