I have server and client socket programs written in C. I want to connect the client program with server program on my laptop using `local host ipaddress 127.0.0.1`. When i execute the server program. its output is binding failed and stops. How to make this possible that is client connecting to server on the same laptop ie through local host. Please Help.

Here is the Server Code(this is a echo server program):

```
#include <stdio.h>
#include <stdlib.h>
#include <sys/socket.h>
#include <netinet/in.h>
#include <arpa/inet.h>
#include <string.h>

main(int argc, char *argv[])
{
    int clilen, sockfd, newsockfd, n, cpid;
    char msg[100];
    struct sockaddr_in serv_addr, cli;
    if ((sockfd = socket(AF_INET, SOCK_STREAM, 0)) < 0)
    {
        printf("socket failed to establish\n");
        exit(0);
    }
    printf("socket created\n");
    bzero((char *)&serv_addr, sizeof(serv_addr));
    serv_addr.sin_family = AF_INET;
    serv_addr.sin_addr.s_addr = inet_addr(argv[1]);
    serv_addr.sin_port = htons(atoi(argv[2]));
    if (bind(sockfd, (struct sockaddr *)&serv_addr, sizeof(serv_addr)) < 0)
    {
        printf("binding failed\n");
        exit(0);
    }
    printf("binding established\n");
    if (listen(sockfd, 5) < 0)
    {
        printf("not listening\n");
        exit(0);
    }
    printf("listening|n");
    for (;;)
    {
        clilen = sizeof(cli);
        if ((newsockfd = accept(sockfd, (struct sockaddr *)&cli, &clilen)) < 0)
        {
            printf("accept failed\n");
            exit(0);
        }
        printf("accepted\n");
        cpid = fork();
        if (cpid == 0)
        {
            n = read(newsockfd, msg, 80);
            msg[n] = '\0';
            write(newsockfd, msg, strlen(msg));
            close(newsockfd);
            exit(0);
        }
    }
}

```
