A couple of questions about C?

I am missing characters in my code. I don't see where I am missing. I was comparing my code in Ch to the code in the book. I don't see a different. I see they are the same.

Code from book:

code:

#include <stdio.h> int main(void)                /* a simple program             */ {     int num;                  /* define a variable called num */     num = 1;                  /* assign a value to num        */     printf("I am a simple "); /* use the printf() function    */     printf("computer.\n");     printf("My favorite number is %d because it is first.\n",num);     return 0;

I don't see a final }.

If you don't see a final. Why is it failing to compile my code as shown above?

If you look at the error, then reread wtd's post, it would make more scene.

{

return 0;
}

[php111]

I got the final }. I get more errors. It's never working for me.

How do I change my syntax file from include to printf? I almost have it.

Re-write the code out in notepad or something, give it correct spacing and indentation.
Trying to look through that is hurting my eyes and it will make it much easier for you to find your mistakes.


Might I also suggest getting away from Ch and use some more native like C?

It's hurting mine as well. I'll be 27 in a few weeks. I have bad eyes since birth. I wear glasses. What do you mean by native C? Don't learn C, and go with something else? I really want to learn C but not with Ch. It was recommended to me.

I tried it in notepad. I am still getting errors. I am just learning. I will post the errors first in a qoute. I will then post my code in code tags.

[/code]

You have written printf twice. You also missed the end }

c:

int main(void) /* a simple program */ { int num; /* define a variable called num */ num = 1; /* assign a value to num */ printf("I am a simple "); /* use the printf() function */ printf("computer.\n"); printf("My favorite number is %d because it is first.\n",num); return 0; }

[/code]


Ch is some sort of rework of the C language. I know nothing about it other then what I have seen in this thread, but it seems to be some sort of learning tool?
I am suggesting you use/write C in the traditional scene.

Open an IDE/Editor (like notepad) type all your code in there, save it with the extension .c (ex. helloWorld.c ) then compile and run the code through either the IDE or command prompt.

[php111]

I done it!!!!!

I used ./the name of my file.c in Ch. I wrote the code using notepad. That was easier then using Ch to write it.

Should I keep writing the same code, or move on? If I write it again then I just delete that code.

Thank you everyone who replied. I wait to see to rewrite or continue.

Congratulations!

Your best bet would be to continue to build off what you know. Perhaps try some arithmetic (add / subtract / divide / multiple your variables)
Learn how to use scanf() (Read formatted data)

The more and more you learn, the easier these last few steps will seem to you.

Do I do that with that printf code above? If so, how do I do that?

Quick examples:

c:

//Addition and Subtraction of integers #include <stdio.h> int main () {         int firstNumber = 3, secondNumber = 2, thirdNumber = 0;         int inputNumber = 0;         printf("This is a test file \n");         //Adding secondNumber to firstNumber         thirdNumber = firstNumber + secondNumber;                 printf("%d plus %d equals %d. \n", firstNumber, secondNumber, thirdNumber);         //Subtracting secondNumber from firstNumber         thirdNumber = firstNumber - secondNumber;                 printf("%d subtract %d equals %d. \n", firstNumber, secondNumber, thirdNumber);                 return 0; }

c:

//Getting integer input from user. #include <stdio.h> int main () {         int firstNumber = 0;         printf ("Enter in a integer : ");                //scanf is used to get input from the user, then places the value into the variable firstNumber         scanf("%d", &firstNumber);         printf ("You entered in %d.\n", firstNumber);                 return 0; }

I got a whole list of errors with your first code.

My errors:
