Thread: What's wrong with my code?

I am writing a client program, simply retreving the HTML code.
However, I only get a error 400
I really don't know what the bug is...
here is the part of sending code

Code:

  char cBuffer[128], cTmp[128];
  const int iBufferLen = strlen(cBuffer);
  while(1){
    printf("\nsend>");
    gets(cTmp);
    if(cTmp == "") {
      printf("Bye Bye...");
      break;
      exit(1);
    }
    printf("Sending...\t\t\t");
    sprintf(cBuffer, "GET /%s HTTP/1.0\n", cTmp);

    if(send(s, cBuffer, iBufferLen, 0) == SOCKET_ERROR) {
      printf("Failed\n");
    }

    printf("OK\n\"%s\" is sent\n", cBuffer);
....

No matter what I type, the received message is always error 400
why ?
