    very very simple question....

    Hi there im in my very first semester of c-programing at uni doing some study at the moment on past exam and im stuck on this question.. well i sorta know it but im wondering what your take on it is.. any help would be much appreciated.

    ......
    Q1, Write a function prototype of a function that dose not return a value and has a single string as an argument.
    ......

    so im thinking of like a void prototype for a function im obviously going to make.. however im not sure how to translate the bit where it dose not return a value and has a string for an argument.??

    You're not being asked to make a function, just to make a prototype. You already have half of it right, since you say you should make a "void prototype." The only other part is the single parameter which is a string. So... Figure out what type a "string" should be and you have your answer.

    okay then so this would be.

    void my_name (char name, "jack");

    void is the prototype, my_name is the function name and char name is the argument with jack as the string.. is that right?.... :S i been reading though my book and notes thats what i have come up with.

    Code:
    void foo(char *);
    7. It is easier to write an incorrect program than understand a correct one.
    40. There are two ways to write error-free programs; only the third one works.*

    "char name" means a single char, not a string of chars. If you look in your book for the section on Strings you should see the correct type to use (it's based on char, but not just "char").

    And because this is a prototype, you don't actually pass a parameter, so the "jack" part is not needed.
