    Question scanf/printf char troubles

    When I run this and enter my name I get a single character output.

    char cName = '\0';

    printf("\n\tGreetings\n");
    printf("\nPlease tell us your name: ");
    scanf("%c", &cName);
    printf("\nWelcome %c", cName);

    this is a challenge question from the Michael A. Vine "C-Programming for the absolute beginner." I believe Ive done everything right here as this same formula has worked for Integers. Do I have to change to this?

    printf("\nWelcome %.10c", cName);

    1) Use code tags please... << !! Posting Code? Read this First !! >>

    2) You should usually post compilable code in case people want to test it.

    3) Read up on strings a little bit more...

    Code:
    char cName[10] = {0};
    
    printf("\nGreetings\n");
    printf("\nPlease tell us your name : ");
    scanf("%9s", cName);
    printf("\nWelcome %s", cName);
    It should come as no surprise that a char can only hold 1 character...
    In C strings are arrays of characters where the last used element of the array is tagged with a trailing 0.
    The library functions cooperate to treat these arrays like text.
