Sockets-programming-in-C

Awesome server and client development in C language

How to use?

1. Compile server.c (in my case, I use gcc compiler, however you might use any C compiler)
2. Execute the compiled server from terminal: ./server
3. Compile client.c
4. Execute the compiled client from terminal

If above steps was successfully done, then client may be able to write to server.

Example

alpha_bank.c is a server side for banking system. To use it, the following steps are required:

1. Compile and execute alpha_bank.c

2. The IP and port number should be printed on the terminal of executed alpha_bank.c:

3. Open another terminal

4. Using telnet service, connect to the IP and port number, for example, just type:

   telnet 127.0.0.1 8888

5. Now you are using a simple ATM, there are two bank accounts with card numbers and balances:

   • char* card_number1="0000 0000 0000 0000";
   • unsigned int balance1 = 1000;
   • char* card_number2="1000 0000 0000 0000";
   • unsigned int balance2 = 1500;

6. ATM asks for card number, just enjoy above numbers

7. Test other functions: BALANCE, WITHDRAW, DEPOSIT between two clients

Give some stars!
