    Better way of declaring char?

    Hi. I came across this piece of code below and was thinking, isn't there a better way of declaring a char for a single character? I also saw the same thing done here

    Code:
      char letter = ' ';
      printf("enter letter\n");
      scanf("%c",&letter);
      printf("print letter %c\n",letter);

    I tried, char letter[0], but it didn't work. I thought it would declare an array of char with 1 element.

    If I entered, char letter; would that be a char of 1 ?

    Thanks

    char letter;
    is fine, since having no brackets would imply that it is no array and an array, by definition, is a collection of n (where n > 1) contiguous elements of the type you declare it to be.
