    Dear all, my I know what's wrong with this error? I want to copy the value from name[j] to the pointer s.

    Arrays are not pointers

    "char s[]" is an array of chars, but "name[j]" is a pointer to char.

    You probably want:
    Code:
    char *s = name[j]

    The line numbers of the posted code don't match the line numbers of the compiler messages.

    Code:

    Line 44:

    What part of "too few arguments to function ‘reverseWords’ " you don't understand?

    The second error is similar.

    What do you think the error messages are trying to tell you?

    Just manage to correct the error with help from someone... But still not very understand about the correct way of link the data in between array to pointer
