a semi colon after return 0..

as he is not replying maybe he has fixed it...?

I will have to fix it once I get home, I see that I have made some silly mistakes and im excited to fix them. Thank u soooooo much for lending knowledge that is much needed. "Class array" yea.. what was I thinking? The typo, it was late and I was frustrated towards the end. I truly thank u guys. If it doesn't compile after my corrections, I'm sorry to say I'll be back.

I also see that I cannot scan input with spaces useing scanf. I think it will be easier to use (gets) and (puts) so the user may use sentences if need be. I hope that I'm making the right decision.

gets is automatically the wrong decision. Try fgets instead.

I replied and don't see it so I will post again. I will make my corrections when I get home and I'm excited about haveing a working program. Im going use (putc) and (gets) instead of printf and scant due to the spaceing issue.

#include <stdio.h>
#include <string.h>

main ()

{

char color [15];
char feet [8];
char food [25];
int age;

fputs ("What color is your hair?\n");
fgets ("%s", &color);

fputs ("%s!, I think u should cut it!!!\n", color);

fputs ("Do u have big or small feet?\n");
fgets ("%s", feet);


fputs ("How old r u?\n");
fgets ("%d", age);

fputs ("Tell me what your favorite kind of food is\n");
fgets ("%s", food);

fputs ("I like %s too!\n", food);

return (0)

}

lol, major bad on that attempt WOW! I'm too tired to research it now so I will try tomorrow after work. I thought it would be much closer than my last one, know one said this was going to be easy and so far it's not.

You have to read that first, before posting code. That is why it's called "Posting Code? Read this First".

fgets is not like scanf, it doesn't take the format of the input as an argument.

(fgets - C++ Reference)

Code:

char * fgets ( char * str, int num, FILE * stream );

str
    Pointer to an array of chars where the string read is stored.
num
    Maximum number of characters to be read (including the final null-character). Usually, the length of the array passed as str is used.
stream
    Pointer to a FILE object that identifies the stream where characters are read from.
    To read from the standard input, stdin can be used for this parameter.

This is the function declaration of fgets, it tells you what you have to give to the function and what it gives to you.

The first thing to supply to fgets is the string where the input is stored. This is the same as the second argument that you usually supply to scanf (well, mostly).

num is how many characters you want to read, as the documentation says just set it to the length of your respective arrays. This is to ensure that the function does not read more than you can store.

the third argument is a little more complicated for beginners, and may not be worth explaining to you in your first program. most simply, you want to read from the keyboard, so provide 'stdin' (without the inverted commas) as this argument.


On another note, statements in C end with a semicolon. return is a C statement.

I refuse to believe that your compiler is not giving you error messages, please post them and try to interpret them.

Im sorry for posting a hope for a quick fix, I was at work and trying to make simple changes to fix my problem. I truly needed to research my second shot a bit more before posting. (Sorry) I truly thank you for your input and will research this while at work. Thank u! Thank u! Thank u!

Well, you see, if you just took the time to learn how the basic functions on C work, I don't think there'd be any confusion on your part.
There are many good tutorials for people who are just getting started like you. Read them carefully. Then look at your code and see what's wrong with it.
