title: C - Reading user input
body: <p>I have a program where user input is required, a user types in a number 1-8 to determine how to sort some data, but if the user just hits enter a different function is performed.  I get the general idea of how to do this and I thought what I had would work just fine but I'm having some issues when it comes to when the user just hits the enter key. Currently my code looks as follows:</p>
  
  <pre><code>//User input needed for sorting.    
  fputs("Enter an option (1-8 or Return): ", stdout);
  fflush(stdout);
  fgets(input, sizeof input, stdin);
  
  printf("%s entered\n", input);  //DEBUGGING PURPOSES
  
  //If no option was entered:
  if(input == "\n")
  {
      printf("Performing alternate function.");
  }
  //An option was entered.
  else
  {
      //Convert input string to an integer value to compare in switch statment.
      sscanf(input, "%d", &amp;option);
  
      //Determine how data will be sorted based on option entered.
      switch(option)
      {
          case 1:
          printf("Option 1.\n");
          break;
  
          case 2:
          printf("Option 2.\n");
          break;
  
          case 3:
          printf("Option 3.\n");
          break;
  
          case 4:
          printf("Option 4.\n");
          break;
  
          case 5:
          printf("Option 5.\n");
          break;
  
          case 6:
          printf("Option 6.\n");
          break;
  
          case 7:
          printf("Option 7.\n");
          break;
  
          case 8:
          printf("Option 8.\n");
          break;
  
          default:
          printf("Error! Invalid option selected!\n");
          break;
      }   
  }
  </code></pre>
  
  <p>Now I've changed the if statement to try input == "", input == " ", and input == "\n" but none of these seems to work.  Any advice would be greatly appreciated.  Currently from what I can see, the initial if statement fails and the code jumps to the else portion and then prints the default case.</p>
  
  <p>Just to be clear the variables I declared for this code are as follows:</p>
  
  <pre><code>char input[2];          //Used to read user input.
  int option = 0;         //Convert user input to an integer (Used in switch statement).  
  </code></pre>
