Raspbian C++ Error: expected primary expression before 'struct' - c++

Question

I am trying to write a program for my raspberry pi that changes its system time to the time from a GPS unit on the same network. The GPS sends out a 72 byte UDP packet across port 3000. I am new to socket programming so I am unsure where I am going wrong.
The trouble that I am having is that I can't seem to get it to build with g++. I am getting the following error:
So the main error seems to be in the line
char A = struct sockaddr_in address;
Here is the start of my program and the method where I create the socket and where the error is located, if you would like the main method of my program then I will add it too.
#include <stdio.h>
#include <sys/types.h>
#include <sys/socket.h>
#include <netinet/in.h>
#include <arpa/inet.h>
#include <stdlib.h>
#include <unistd.h>
#include <string.h>
#include <time.h>
#include <sys/time.h>
#include <errno.h>
#include <math.h>
// defines the socket used by the GPS
#define PORT 3000
/****************************/
int CreateSocket(int port)
/****************************/
{
// Create an UDP-socket
int sock = socket(AF_INET, SOCK_DGRAM, 0);
// Check if UDP-socket was created
if(sock==-1)
{
fprintf(stderr, "1CreateSocket: socket failed\n");
return -1;
}
// Bind it to the local IP-address
struct sockaddr_in address;
char A = struct sockaddr_in address;
fprintf(stderr, A);
// Pointer to the block of memory to fill with address data
memset(&address, 0, sizeof(address));
address.sin_family = AF_INET; // Address family for IP-address
address.sin_addr.s_addr = htonl(INADDR_ANY); // converts the unsigned integer hostlong from host byte order to network byte order
address.sin_port = htons(port); // converts the unsigned short integer hostshort from host byte order to network byte order
// Check if IP-address is correct, if not Socket failed. Otherwise it returns the socket
if(bind(sock, (struct sockaddr *) &address, sizeof(address))==-1)
{
fprintf(stderr, "2CreateSocket: bind failed\n");
close(sock);
return -1;
}
return sock;
}
Can anyone see any obvious errors here? Thanks

You don't really need these two lines:
char A = struct sockaddr_in address;
fprintf(stderr, A);
You can delete them, since they don't do anything useful, and they have a syntax error.
And to do some extra cleanup, the comment of the binding above those lines that can be deleted should actually go above the call to bind().
