Some TCP states not showing in the terminal

I have written a basic client server code to understand the TCP states. Client code :

#include <stdio.h>
#include <sys/socket.h>
#include <netinet/in.h>
#include <string.h>

int main(){
int clientSocket;
char buffer[1024];
struct sockaddr_in serverAddr;
socklen_t addr_size;

/*---- Create the socket. The three arguments are: ----*/
/* 1) Internet domain 2) Stream socket 3) Default protocol (TCP in this case) */
clientSocket = socket(PF_INET, SOCK_STREAM, 0);

/*---- Configure settings of the server address struct ----*/
/* Address family = Internet */
serverAddr.sin_family = AF_INET;
/* Set port number, using htons function to use proper byte order */
serverAddr.sin_port = htons(7891);
/* Set IP address to localhost */
serverAddr.sin_addr.s_addr = inet_addr("127.0.0.1");
/* Set all bits of the padding field to 0 */
memset(serverAddr.sin_zero, '\0', sizeof serverAddr.sin_zero);  

/*---- Connect the socket to the server using the address struct ----*/
addr_size = sizeof serverAddr;
connect(clientSocket, (struct sockaddr *) &serverAddr, addr_size);

/*---- Read the message from the server into the buffer ----*/
recv(clientSocket, buffer, 1024, 0);

/*---- Print the received message ----*/
printf("Data received: %s",buffer);   

return 0;
}

Server Code :

/****************** SERVER CODE ****************/

#include <stdio.h>
#include <sys/socket.h>
#include <netinet/in.h>
#include <string.h>

int main(){
int welcomeSocket, newSocket;
char buffer[1024];
struct sockaddr_in serverAddr;
struct sockaddr_storage serverStorage;
socklen_t addr_size;
welcomeSocket = socket(PF_INET, SOCK_STREAM, 0);
serverAddr.sin_family = AF_INET;
serverAddr.sin_port = htons(7891);
serverAddr.sin_addr.s_addr = inet_addr("127.0.0.1");
memset(serverAddr.sin_zero, '\0', sizeof serverAddr.sin_zero);  

bind(welcomeSocket, (struct sockaddr *) &serverAddr, sizeof(serverAddr));

if(listen(welcomeSocket,5)==0)
printf("Listening\n");
else
  printf("Error\n");

addr_size = sizeof serverStorage;
newSocket = accept(welcomeSocket, (struct sockaddr *) &serverStorage, &addr_size);

strcpy(buffer,"Hello World\n");
send(newSocket,buffer,13,0);

return 0;
}

I am running the command netstat -an | grep 7891, so at various points of time, I am getting the states ESTABLISHED, LISTENING, FINWAIT2, CLOSE_WAIT and TIME_WAIT. How to get the other states like SYN_RECV, SYN_SENT, FINWAIT1, CLOSING and LAST ACK.

I have tried with various netstat options and ss options but to no vain.
