socket only connection

Language: C Socket Connection

To establish a socket connection in C, you can follow these steps:

  1. Include Necessary Libraries:

  2. Include the necessary libraries for socket programming in C, such as #include <sys/socket.h> and #include <netinet/in.h>.

  3. Create a Socket:

  4. Create a socket using the socket() function, which takes parameters for the address domain, socket type, and protocol. For example: c int sockfd = socket(AF_INET, SOCK_STREAM, 0);

  5. Specify the Address and Port:

  6. Define the address and port to connect to using a struct sockaddr_in and set the address and port in the structure.

  7. Connect to the Server:

  8. Use the connect() function to establish a connection to the server. For example: ```c struct sockaddr_in server_address; server_address.sin_family = AF_INET; server_address.sin_port = htons(PORT); server_address.sin_addr.s_addr = inet_addr("127.0.0.1");

    int connection_status = connect(sockfd, (struct sockaddr *)&server_address, sizeof(server_address)); ```

  9. Handle Connection Status:

  10. Check the connection status to ensure the connection was successful.

  11. Send and Receive Data:

  12. After the connection is established, you can use send() and recv() functions to send and receive data over the socket.

These steps will allow you to create a socket connection in C and communicate with a server.
