Client and Server program gen by Makefile

I created a "ebanking.x" file and run it as " rpcgen -a ebaning.x"
It gen a few of files to me which is - "ebanking.h", "ebanking_server.c", "ebanking_svc.c", "ebanking_client.c", "ebanking_clnt.c", "ebanking_xdr.c" and "Makefile"

The content of "ebanking.x" :

struct bankargs {
  char usr_id[10];
  char usr_name[40];
  int usr_account_num;
  double balance;
};

program BANKING_PROG {
  version BANKING_VERS {
    int VIEWBALANCE(bankargs) = 1;
    int TRANSFER(bankargs) = 2;
    string SYNDATA() = 3;
  } = 1;
} = 8431;

I try to add some code in "ebanking_server.c" & "ebanking_client.c" files:

"ebanking_server.c":

char svrname[100];
main(int argc, char* arg[])
{
	void* argp;
	if(argc<2)
	{
		printf("Usage: %s <Server Name> \n",arg[0]);
		exit(0);
	}
	strcpy(svrname,arg[1]);		
	printf("This Server: %s\n",svrname);	
}

"ebanking_client.c"

char usr_id[10], usr_name[40];
char *primary;

void clear() {
	system("clear");
}

void loadmenu() {
	char choice;
	int i;
	printf("\n\nCurrent user: %s\n", &usr_id);
	printf("=================================\n");
	printf("1. View Balance               2. Transfer\n");
	printf("3. exit (program)\n");
	printf("Please enter your choice: ");
	scanf("%s", &choice);
	if (choice == '1') {		
	  view_balance();	  
	} else if (choice == '2') {	  
	  transfer();		
	} else if (choice == '3') {
	  printf("Thank you for using the system\n");
	  exit(0);
	}
}

main(int argc, char *argv[])
{
	if (argc < 2) {
		printf("usage:  %s <Type server name>\n", argv[0]);
		exit(1);
	}
	primary = argv[1];
	clear();
	printf("Please enter User ID: ");
	scanf("%s", &usr_id);
	printf("Please enter User Name: ");
	scanf("%s", &usr_name);
	strcat(usr_name, "\n");
	while (1) {
		loadmenu();
	}
}

What doi want to do now? I have tried to compiler it and it prompt error.
type "make" to gen more files and i type "ebanking_server <server name>"
On the othre hand, would you teach me how to make a ebanking_server file after execute, it can still execute and listening for the ebanking_client execute to do some process and ommunication
for instance:
i type "View balance" in client side, server can get the request from client and send the balance to client view

Thank you very much for helping me

Or i post all my files on this site, you can download the files from this file for you to easier for helping me. Thanks
