langkah langkah menjalankan program
1. simpan program dengan nama client.c dan untuk server dengan nama server.c
2. lakukan instalasi compiler untuk c pada linux
3. #yum install gcc
4. lakukan kompilasi progaram
5. gcc client.c -o client
6. gcc server.c -o server
7. jalankan program server dan client
8 #./server
9. #.client <ip server>
output server
output client
