client-server chat application in C
I am doing this simple client-server chat application in C, to establish socket connection between client and server, and exchange messages between them.
I am able to implement this on 2 different terminals on the same computer.
I want to know how to implement this on two different computers, that is, by dynamically passing IP address and port number during run time.
I am using the following code(Attachments provided)

//TCP Client #include<sys/socket.h> #include<stdio.h> #include<string.h> #include<netdb.h> #include<stdlib.h> int main() { char buf[100]; int k; int sock_desc; struct sockaddr_in client; memset(&client,0,sizeof(client)); sock_desc=socket(AF_INET,SOCK_STREAM,0); if(sock_desc==-1) { printf("Error in socket creation"); exit(1); } client.sin_family=AF_INET; client.sin_addr.s_addr=INADDR_ANY; client.sin_port=3002; k=connect(sock_desc,(struct sockaddr*)&client,sizeof(client)); if(k==-1) { printf("Error in connecting to server"); exit(1); } while(1) { printf("\nEnter data to be send to server: "); fgets(buf,100,stdin); if(strncmp(buf,"end",3)==0)//Use to end communication with server break; k=send(sock_desc,buf,100,0); if(k==-1) { printf("Error in sending"); exit(1); } k=recv(sock_desc,buf,100,0); if(k==-1) {Â

printf("Error in receiving"); exit(1); } printf("Message got from server is : %s",buf); } close(sock_desc); exit(0); return 0; }Â

} close(temp_sock_desc); exit(0); return 0; }
